Quality of Contact Stats (Soft%, Med%, and Hard%) represent the percentage of a hitter or pitcher’s batted balls that have been hit with a certain amount of authority. The percentages will sum to 100%, totaling all of a player’s batted balls hit or allowed. While a lot of statistics are based on the outcome of the play (i.e. hit or not), quality of contact stats are more like pitch velocity in that they define a process that occurred en route to an outcome.
