Our draft ranks have finally come to an end.

As the countdown for the MLB Draft reaches single digits, our content coverage of the prospects whose names may be called on June 10th/11th has significantly sped up. After breaking down all the positional prospects that we believe are worth mentioning, we ranked the top 30 right-handed pitchers from this class. Today, we completely wrap up our draft rankings with our final installment: the southpaws.

This group isn’t as deep as their counterpart right-handers, but that doesn’t mean there isn’t talent littered throughout this list. Asa Lacy headlines this bunch as the top arm in the class, Garrett Crochet’s upside is sky high, and both Reid Detmers and Logan Allen have solid big league futures as back-of-the-rotation arms. It’s certainly an interesting collection of arms that need to be noted.

After several hours of churning through video and information, these are the consensus rankings agreed upon by both of our draft analysts. Without further delay, let’s get into it:

 

1. Asa Lacy, 21 years old, Texas A&M

The top pitcher on most teams boards, there isn’t much to not love about Asa Lacy. If we were basing evaluation off pure track record alone, Lacy’s production at Texas A&M tops virtually anyone in the draft. His strong and sturdy 6-foot-4, 215-pound frame is an ideal frame for him to hold innings deep into a 162-game season. 

You’ll be hard-pressed to find a fastball better than Lacy’s in this class, regularly sitting in the 94-97 mph range and working on a downhill plane, getting some fairly ugly swings from opposing bats. He throws two breaking balls, both hard and with conviction, but each has its own distinct break. His curveball shows a tight 1/7 shape with downer actions, while the slider is arguably the best overall pitch in the entire draft. It’s tight, tunnels well off his fastball, and is already a true big league swing-and-miss pitch. Lacy also features an above-average changeup with natural fade, giving him four above-average to plus offerings. While he’s a damn good pitching prospect, Lacy is just like everyone else and isn’t perfect. His delivery is a bit quirky and he doesn’t have excellent command right now, but notice that he’s still been extremely effective lacking that plus control. A couple of mechanical tweaks, including extending his stride downhill, could help lower the walk numbers and increase his overall production more. Lacy has the makings of a bonafide top-of-the-rotation pitcher. 

2. Garrett Crochet, 21 years old, Tennessee

Barely 21 years old, Crochet represents one of the younger college pitchers available in this year’s draft and a damn good one at that. The biggest question mark on Crochet’s profile is whether or not he’s going to be a starting pitcher or end up in the bullpen. The stuff is absolutely electric, and he’s got a proven track record starting. Crochet has run into some arm fatigue in the past, and he’s been known to get a tad erratic from time to time. From this chair, you’re looking at a shutdown reliever at the next level. 

Crochet arguably has one of the best fastballs in the entire draft. Working out of a low, three-quarter slot, the Volunteer touches 100 in bullpen work and comfortably sits 95-98 in-game. There are some herk and jerk to his motion, but it’s deceptive and allows for his pitches to tunnel off each other beautifully. The slider is yet another plus-plus offering. Running through the zone in the high 80s, Crochet’s breaking ball comes out of the exact same deceptive arm slot as the fastball and shows deep lateral action and some vertical tilt. The two-pitch mix, as well as the delivery, are eerily similar to Josh Hader’s profile. There’s also a changeup and a curveball, the former being a little more advanced than the latter. If he were to move into a relief role, Crochet should dump the curveball and focus exclusively on his two plus-plus bread and butter offerings while occasionally working in the potential 55-grade changeup. 

3. Reid Detmers, 21 years old, Louisville

Detmers was the undisputed ace of an extremely talented Louisville rotation this season, one that could potentially include another first-round pick in Bobby Miller. His stuff isn’t nearly as overpowering as some of the true power pitchers on this list, but Detmers uses a combination of deceptiveness and elite command to unlock a new level in his repertoire. Detmers fastball works in the 90-94 mph range with natural lefty arm-side run to it and plays up because of that aforementioned deception. He’s known for a high-spin curveball that sits between 73-76 mph and profiles as a plus pitch long-term. Detmers also throws a changeup, but it doesn’t project more than an average pitch. There’s little risk in taking Detmers because you already know what he’s going to be: a command-oriented big league lefty that’s going to fill up innings towards the back of a rotation. 

4. Dax Fulton, 18 years old, Mustang HS (OK)

Dax Fulton is truly just scratching the surface to what he could eventually become. At 6-foot-6, 230 pounds, Fulton is already equipped with a grown man body, a physique that isn’t soft either. The Oklahoma hoss was squarely in the conversation with guys like Mick Abel and Jared Kelley last summer before tearing his UCL, forcing him onto the shelf and absent from the 2020 circuit. Nobody’s seen Fulton throw in more than a year, but that hasn’t stopped scouts from flocking to his side when asked about his potential as a big-league starter. Fulton will be fully healed and ready to pitch this fall. 

As you might imagine, a guy of his size packs some pretty good gas in the tank. Last spring, Fulton was comfortably sitting 90-93 with natural cutting action on his fastball. Most scouts believe there’s far more in profile, assuming he’ll likely end up in the 95-96 range in his prime. While the fastball is impressive, Fulton may have the best true curveball in the class. It’s a power offering with 11/5 break. The pitch sits in the upper 70s right now, creating a good bit of separation off his stiff heater. At 17 years old, Fulton was commanding the pitch with ease, leading some to believe it’s a plus offering as a floor. He mixes in an inconsistent changeup as well that was showing promise before he was shut down. With three pitches, two of which have already shown plus or better potential, Fulton has the making of a top of the rotation arm that should move quickly for a prep, so long as his health permits. 

5. Ian Seymour, 21 years old, Virginia Tech

Up until 2020, Ian Seymour wasn’t regarded as a premier pitching prospect. That changed after his shortened junior year. Traditionally 90-92, Seymour saw his fastball touch 95 this season, resulting in far more strikeouts, far fewer walks, and a minuscule ERA. The Hokie projects as a solid mid-rotation starter at the next level so long as the organization that selects him does not try to move him into a bullpen where his stuff may tick up another notch. 

The fastball is now a plus offering, sitting 92-95. Seymour has been known to tinker with its grip now and again, manipulating spin and creating some cut action to the pitch. This differs from his true slider that flashes now and again, drawing above average-to-plus grades from scouts. His third offering is a changeup that more often than not grades out as a 55 offering, also flashing plus now and again. It’s a three-pitch mix that should develop well in a starter role. There’s some effort in his delivery, but that shouldn’t stop him from reaching his ceiling as he’s a strike-thrower and limits free passes. 

6. Jared Shuster, 21 years old, Wake Forest

Shuster significantly improved his draft stock this spring, albeit in a small sample size. His physicality is the first thing that stands out is impressive, standing at a strong 6-foot-3, 215-pound frame. While his delivery is quirky and unconventional, Shuster does actually repeat it well and has the size to stick in a rotation long term. 

The uptick in his stuff is a big reason why Shuster has vaulted himself into first-round discussions. His fastball came out of the gates this spring sitting 92-94 mph and touching 97 mph with late riding action to it. There’s no denying the effectiveness of his plus changeup from the left side and its natural downward tumble allows it to pair perfectly with his fastball. Most left-handed pitchers typically post high-spin rates on breaking balls, but that isn’t the case with Shuster. When he does manage to effectively spin something, it plays more like a slurve and the consistent feel for it just isn’t there. Shuster’s upside is undeniable and he’s likely to go in the top 40 picks as things stand right now. 

7. Logan Allen, 21 years old, FIU

Allen is virtually the definition of a soft-tossing, command-oriented southpaw. He’s only six feet tall and roughly 180 pounds, but his ability to consistently spot-up three pitches for strikes allows his stuff to play up. Allen’s fastball works around 89-91 mph, touching 93 mph occasionally and playing with plenty of late arm-side run. He’ll consistently dot it up to either corner of the plate and is excellent at getting ahead of hitters early. From a stuff perspective, Allen’s changeup is the best pitch in his arsenal. It looks exactly like his fastball coming out of the hand and then just drops off a cliff, flashing plus actions. Allen’s feel to spin is above-average, although his breaking ball does get loopy at times and hangs over the heart of the plate too much. It is an average third pitch, however, and gives him a solid three-pitch repertoire to build off once he becomes a professional. Similarly to Detmers, Allen’s pitch ability will carry him through the minors and into the big leagues as a safe back-end starter. Don’t be surprised if he’s one of the first players from this class to make his debut. 

8. Sam Weatherly, 21 years old, Clemson

Sam Weatherly doesn’t project all too dissimilar to the aforementioned Seymour. A two-pitch pitcher with a bullpen likelihood, Weatherly should move through the low minors very quickly as he works to debut as early as 2021. Weatherly’s track to this point has been far different than Seymour. The Clemson Tiger has been on scouts radars for the better part of five years. In high school, Weatherly had a build that most scouts felt would tack on strength, supplementing his already live arm. That has certainly happened during his time on campus. 

At 6-foot-3, 205 pounds, Weatherly certainly looks the part. It’s a clean, repeatable delivery, though his mechanics haven’t helped him avoid free passes. In 22 innings his junior year, Weatherly walked 14 batters. He punched 43 tickets in the process, but those base on balls lead most to believe he’s a bullpen arm at the next level. The fastball is a plus pitch at 93-95. He works in an equally impressive plus slider and occasionally throws a changeup. Weatherly is a fairly polished profile for what he is. He’s likely a 3rd or 4th round pick. 

9. Kyle Harrison, 18 years old, De La Salle (CA)

Harrison garnered some early attention by some draft individuals, including me, as the potential top left-handed pitching prospect in this year’s prep class. We didn’t see an uptick in the stuff coming out of the gates this spring, and Fulton’s upside is ultimately higher, but Harrison is still an intriguing draft prospect nonetheless. 

A lean, athletic 6-foot-2, 200-pound southpaw, Harrison has plenty of room to fill out his frame and add 10-15 more pounds of muscle as he continues to grow. His fastball sits between 90-93 mph, coming clean out of the hand and with life into the zone. It’s difficult to square his heater up, and all of his pitches for that manner, because he attacks hitters from a deceptive ¾ arm slot that is somewhat reminiscent of Chris Sale’s FGCU days. When Harrison gets ahead in the count he’ll turn to a sweeping slider as his put-away pitch and it has flashed plus actions in the past. His changeup is thrown with fastball arm speed but is a bit flat and doesn’t project as anything more than a change-of-pace pitch. Harrison’s frame and pitch ability suggest there’s more to unlock and he would benefit greatly from going to UCLA, a program known for developing talented high school pitching prospects into pro-ready arms. Should he one day become a Bruin, keep your eyes peeled for him in the first round of the 2023 MLB Draft. 

10. Burl Carraway, 21 years old, Dallas Baptist

If you take Crochet out of the equation, Carraway is unequivocally the best lefty reliever in this class. The only thing pushing him down this list is his role. Some of the aforementioned guys like Seymour and Weatherly have a shot at being starters at the next level. Carraway does not. That being said, there’s a legitimate case to be made that Carraway will have a bigger impact than at least half of the names above him on this list. 

Just six feet tall, weighing a shade over 170 pounds, Carraway is a slender build with a live, explosive arm. The fastball is a plus offering sitting around 97 most nights. Besides the heather, Carraway employs a plus breaking ball that generates a ton of swing and miss. The wart on his game is the command. If he can hone in the control for his two-pitch mix, there’s reason to believe Carraway could pitch in 2020 for a big league club, especially given the taxi squad idea being thrown around. The command is the only thing holding him back from moving extremely quickly. We’ve got this guy slotted as the first player to debut from the 2020 MLB Draft. 

11. Jake Eder, 21 years old, Vanderbilt

Somewhat of an outcast on Vanderbilt’s loaded roster, Eder would certainly be an impact starter on several teams across the country. A physical 6-foot-4, 220-pound southpaw, Eder’s intriguing performance on the Cape this summer certainly boosted his draft stock. At peak, Eder’s fastball sits between 92-94 mph, touching 96 mph at times. His inability to consistently hold velocity from start to start is concerning, and probably the reason he’s this low on our list, as we’ve seen him come out throwing 90-91 mph a few days after registering higher velocities. Eder’s curveball is his best pitch, although there are some outings where he just doesn’t have a feel for it, just like his fastball. His changeup is a below-average offering right now and he just needs to throw it more for more comfort. Eder can be flat out dominant on any given day while also looking like a completely different arm on another. His inconsistency issues continue to plague him, but there will always be upside. 

12. Ricky Tiedemann, 17 years old, Lakewood (CA)

Our second prep on the list, Tiedemann won’t be 18 years old until October. He’s incredibly young for the class, and for that reason, will be enticing for player development programs. Tiedemann could quite possibly play centerfield at the next level, he’s that kind of freak athlete. He runs well, fields his position at an elite level, and has a livewire arm on the mound. There’s a ton of projection here. 

Already 6-foot-3, 200 pounds, Tiedemann just looks the part. His fastball sits in the low 90s right now, but most would be stunned if he’s not sitting 94-95 by the time he’s fully developed. He works in two developing pitches in the slider and changeup, though neither are even above average offerings at this time. There’s a ton to like about the University of San Diego commit, but he’s going to be a project. He’ll likely require five full years in a minor league system before debuting, but when that day comes, he could be special. If the secondary pitches develop into a plus, or even above-average offerings by 2023, Tiedemann could quite easily be a Top 15 selection. 

13. Luke Little, 19 years old, San Jacinto JC (TX)

Many became infatuated with Little a few weeks ago after a video surfaced of him hitting an absurd 105 mph with his fastball. While there’s certainly a lot to love, and he’s at the premier pitching JUCO for pitchers right now, Little does have his fair share of mechanical flaws, including an unconventional delivery that includes a fairly prodigious head whack. Little does have that ridiculous fastball power in his 6-foot-8, 225-pound frame, but he struggles to repeat his delivery and doesn’t hold velocity into starts, typically sitting in the 93-96 mph range. He struggles to throw any of his off-speed pitches for strikes and even struggles to locate the fastball as well. Little has the loud tools that give him a high ceiling, but even the floor is fairly low. 

14. Seth Lonsway, 21 years old, Ohio State

We may be a little lower than some other pundits on Lonsway, but after watching him in action during the 2019 Cape Cod League, we were left unimpressed. Lonsway is fully capable of being a starter at the next level, which should help him in getting selected in the first few rounds of the 2020 draft. He’s a four-pitch guy that has shown a glimpse of spotting all four offerings. 

The fastball is currently a fringe-average pitch. The velocity is there, comfortably sitting in the low-90s, but the feel for the pitch is not. Lonsway walked 12 batters in 12 innings last summer, and a lot of that was thanks to falling behind in counts and not being able to spot the heater. He mixes in a slider, curveball, and changeup, all of which have flashed above average at times, though are generally regarded as average offerings. It’s a slate of pitches, which you don’t find from most lefties in college. If the fastball command doesn’t improve, he too will be destined for a bullpen. 

15. Nick Swiney, 21 years old, NC State

Swiney has served as both a starting pitcher and reliever for the Wolfpack over the last three seasons. He excelled out of the bullpen, where his fastball velocity played up into the low-to-mid-90s and led to his potential plus breaking ball just being flat-out more effective. They then moved him into their rotation and his fastball velocity dipped down. Swiney contributed quality innings for the Pack, but he was ultimately more valuable to them out of the bullpen, where he profiles best in the long-term. He’s got the stamina-experience combination to be a spot starter here and there, but Swiney’s ultimate role is as an effective long reliever. 

16. Adam Seminaris, 21 years old, Long Beach State

Like Lonsway, Seminaris is a four-pitch guy. He more comfortably projects as a big-league starter, thanks to his superior command and pitch ability. Unlike Seminaries, however, his stuff isn’t quite so electric. A finesse guy, the Long Beach State product does a very good job of keeping hitters off-balance and staying ahead in the count. 

The fastball is high-80s, touching low-90s. He has two distinct breaking balls, one big bender picturesque curve, as well as a slurvy slider that adds a few ticks on the radar gun. Both are hard to sit on as he does a good job commanding them. They’re average offerings by nature and spin, but get high marks for location. There’s also a changeup that he plays well off his fastball. Seminaris is a high floor, low ceiling guy that should eventually reach his backend of the rotation role. 

17. Mason Miller, 18 years old, Mitchell HS (Fl.)

Miller was trending upward prior to the 2020 MLB Draft cancellation and he’s someone who could sneak his way into later rounds of the draft. He has the frame at 6-foot-3 and 200 pounds to project as a starting pitcher long term and, while his overall feel to pitch is raw right now, has some intriguing upside on the mound. 

Miller’s fastball ranges anywhere from 88-92 mph with late arm-side run that comes from a clean ¾ arm slot. There’s more velocity left in the tank and some efficient mechanical tweaks could ultimately have him sitting in the 92-94 mph range sooner rather than later. Miller’s money pitch is a high spin breaking ball that has flashed plus potential at times. It has both elite shape and depth, giving him an already big-league ready pitch in his arsenal. He doesn’t really throw anything other than those two pitches, which has to be the obvious knock on him, and the control is average at best at the moment. However, Miller’s projectability could lure some team into throwing a decent amount of money at him to sign. 

18. Timmy Manning, 18 years old, Cardinal Gibbons (Fl.)

Timmy Manning has long received high marks for his ability to spin a baseball and feel to spot those breaking balls. Committed to Florida, Manning looks like the next weekend staple for the Gators in the coming season’s thanks to his advanced resume. He’s likely a seven-figure sign if selected this year, a tough ask for teams generally looking for velocity from preps. 

The fastball is usually 87-90 with some natural cut. He commands the ball well and gets ahead of hitters regularly. Manning is advanced enough where he currently throws his breaking ball on 0-0 counts as a get-ahead pitch, a trait seldom seen at the high school ranks. The plus breaking ball is a low-80s offering. He also mixes in a changeup that has a ways to go on the development curve. At 6-foot-2, 175 pounds, Manning isn’t too dissimilar from Jack Leiter at this time last year. If he adds a few ticks to the radar gun and the changeup takes a step forward, he could easily be a day one pick in 2023 should he end up on campus like expected. 

19. Michael Kirian, 21 years old, Louisville

Kirian was on fire early into the season as Louisville’s closer. He completed all of his save opportunities (six), retired almost 90% of the batters he faced, and did not allow an earned run to cross the plate. Standing at a truly massive 6-foot-6 and 235 pounds, Kirian repeats his mechanics well and fills up the zone more than most people his size. His fastball usually ranges in the high-80s to low-90s, but his arm action is deceptive and he uses his size to make every at-bat as uncomfortable as possible for opposing hitters. Kirian’s slurve is just okay, showing some feel to spin and not much depth to it. Kirian could ultimately return to Louisville and hope to build off that dominant run he started this season. There isn’t much professional upside to him right now. 

20. Ryan Bruno, 18 years old, American Heritage (FL.)

Command, command, command. That’s the story of Ryan Bruno. If he threw more strikes, Bruno would likely rank in the top ten on this list. The velocity is there, the spin rate is there, and the body and delivery are projectable. A Stanford commit, it’ll be pretty difficult to dissuade him from his collegiate commitment. The Cardinal churns out solid arms on a yearly basis and Bruno presumes to be the next in line. 

The fastball is easily 92-93 mph but can touch 95 mph when he’s revved up. But it’s a legitimate 30-grade command right now, and that can’t be overstated. Bruno mixes in a curveball, slider, and a changeup, all of which are in such a developmental stage, it would be an injustice to grade them right now. Bruno could end up at the backend of a team’s bullpen or the frontend of a team’s rotation. The ceiling-floor is that wide right now. We’ll have a much better idea of who he is on the mound in 2022 and 2023 when his role becomes clear.
