With below average depth, break, and velocity (82.4 mph), the slider was not effective in 2019 for Alvarez with the league slugging .609 against it with a .412 wOBA. Alvarez does get a few whiffs (12.1% SwStr) and can throw it for strikes (45.5% zone), but perhaps should do so less often, allowing a 84.6% Z-Contact with it.
