BA on a couple of under the radar Jays pitchers with great sliders:
Dahian Santos, RHP, Blue Jays
The Blue Jays have had a banner year for pitching on the farm. Despite trading away 2021 first-rounder and highly regarded college starter Gunnar Hoglund, the Jays saw several breakouts on the pitching side this season, highlighted by Ricky Tiedemann, Yosver Zulueta and Hayden Juenger. One of the brightest breakouts was the 19-year-old Santos. The righthander performed well over 19 appearances with Low-A Dunedin before seeing a late-season promotion to High-A Vancouver. The undersized righthander has an unusual operation and arm action that allow his pitches to play up, particularly his slider. Santos utilizes a tall-and-fall operation with a low sidearm action that plays up his horizontal movement upon release. As you would expect from any low-slot slinger, Santos’ slider generates heavy sweep. Sitting 80-82 mph with 2,700-2,800 rpm of raw spin, Santos generates on average 14 to 15 inches of sweep with very little to no vertical break. The pitch is Santos’ go-to offering, seeing nearly identical usage to that of his fastball. While still learning to command the pitch, Santos generates whiffs on 57% of swings and chases on 35% of swings. In a breakout season for Santos, his slider was the nucleus of his success.
Trent Palmer, RHP, Blue Jays
Drafted in the third round of the 2020 draft out of Jacksonville, Palmer tosses one of the filthiest sliders in the minors. The sweeper Palmer throws is unusual due to the amount of vertical break he generates while simultaneously getting on average 10 inches of horizontal break. Palmer utilizes a low sidearm action that allows the ball to play up out of his hand. This works particularly well when Palmer throws his slider as it has elements of its movement profile that are in-line with cutters while getting more horizontal break than a cutter. It’s a truly unique pitch. Sitting 80-83 mph with spin rates in the 2,300-2,400 rpm range, Palmer generates a foot of ride with 10 inches of horizontal break. That combination of movement and unique release characteristics drove success for Palmer’s slider in 2022. The righthander generated whiffs on 33% of swings against the pitch while getting chases at an average rate. Palmer’s slider graded out the highest of his pitches on Stuff+ models, with grades north of 140.
