While Kinley’s fastball did hold batters to a .267 average, eight of the 20 hits allowed went for extra-base hits (three home runs and five doubles) and coupled with the 15 walks given up, batters ended the season with an OBP of .396 against it. In addition, he lost 2 mph of velocity from last year, dropping from 97 to 95.
The slider was Kinley’s primary pitch in 2019, stifling opposing batters to a .210 BBA and a .067 ISO. Despite a 13.4% strikeout rate drop from a limited appearance in 2018 (44.4%) to 2019 (31%), Kinley’s walk rate didn’t follow suit, only falling from 16.7% to 15.1%.
While Kinley’s fastball has all the velocity (96.7 mph average, 99.1 mph max velocity) necessary to be good fastball, it’s far too straight a pitch to be effective. Putting together a K-BB% of just 3.0%, this pitch got whacked around when contact was made, as it gave up a .367 BAA with a .300 ISO and 204 wRC+.
Thrown 80 times in 2018, Kinley’s slider managed to check two of the three Money Pitch check boxes with 44.2 O-swing% and a 23.5 SwStr%. If he can start to throw it in the zone more often (35.8 zone%), then this pitch could be devastating. Boasting a 44.4 K% and an 83.3 GB%, Kinley’s slider held hitters to a .214 BAA with a .071 ISO—good for a 112 wRC+.
