Parsons debuted for the Braves in 2018 in a spot start that went terribly. A trade to the Rockies saw him move to the bullpen, and things didn’t fair any better for the 27-year-old. The changeup is middling at best; it has above average vertical drop, but Parsons left it too high in the zone on a number of occasions. It went for two homers in just 40 pitches. More work is necessary in the offseason.
It wouldn’t be surprising to see Parsons use the curve more in 2020 due to the problems with his other offerings. It is hard to get a good feel for the pitch after seeing it just 11 times last season, but much like his changeup, Parsons achieves decent vertical drop.
Parsons significantly reduced the usage of 93.3 mph sinker last season, which was not surprising as hitters clobbered a .400 BA against it in 2018. His command of the pitch was erratic at best, and a nasty .461 xWOBA in 2019 suggests there is no light at the end of the tunnel for Parsons here.
Parsons found a swing-and-miss pitch in his slider in 2019. His 15 Ks, commanding a 30.6 whiff rate, probably kept him from being sent down to work on his other pitches.
His most thrown pitch at 48.8%, Parsons’ sinker averaged 90.7 mph and topped out at 92.6 mph. It showed below-average drop at 22 inches (26 inches was league-average drop).
Parsons’ slider averaged 86.5 mph and showed well-below-average horizontal movement at two inches and drop at 30 inches (league average was six and 37 inches, respectively).
Parsons’ changeup averaged 84.1 mph and showed above-average horizontal movement toward a righty at 16 inches and above-average drop at 35 inches (league average was 13 and 32 inches, respectively).
Wes Parsons only threw five innings in 2018. His fastball averaged 91.9 mph and topped out at 93.2 mph. It showed above-average movement toward a righty at 11 inches (league average was seven inches) and above-average drop at 17 inches (16 inches was league-average drop).
