The change was not a significant part of Adams’ arsenal in 2019, used 6.9% of the time overall and almost exclusively against left-handed batters. It tends to be pretty straight with below-average drop and exhibits only mediocre velocity separation from his fastball (6 mph). It was not in the zone often (26.3%), also failing to register any swinging strikes in 36 tries and was put in play four times, two going for hits.
Adams showed a slight affinity for his curve (17.5%) over his slider in 2019, especially as his go-to against left-handed batters. While employed most often when ahead in the count, it nonetheless did not produce an elite chase (26.7%) or whiff rate (10.5%), with below-average drop but good sweeping action and was squared up when contact was made (.750 SLG against).
Despite good natural sink to go with average velocity (91.7 mph), Adams’ fastball was not terribly effective in 2019, getting a 35% ground ball rate and allowing a 1.158 OPS against. It did register a decent 8.2% SwStr rate and a xwOBA of .392 versus the actual .441 mark, so maybe better (though not exceptional) times are ahead.
With about 4 mph on his curve, the slider demonstrates less drop and run and is Adams’s primary breaking ball against RHB. Like his curve, it registered middling chase (30.5%) and whiff (6.2) rates and was hit to the tune of a .341 wOBA, though with a .223 xWOBA he may have been victimized by some bad luck on balls in play in 2019.
Adams’ four-seamer was straighter and got less ride than is typical over 102 pitches in ’18. It showed little swinging-strike and chase potential and carried a 16.7 walk percentage. Hitters also banged it around for a .350 ISO. Ouch.
This hook showed promise in the movement department with above-average bend. And though it’s tough to glean much from 29 pitches, it did carry a promising 40% chase rate last year.
The 24-year-old’s slider displayed above-average bend and a good chase rate (38.9%), though that came over just 22 pitches. Based on movement alone, it looks like Adams could have a solid secondary.
