The fastball is Baez’s calling card. It sits in the mid 90s, touching 97 mph, and Baez pounds it high on the glove side more often than not. It has good ride and misses bats at a 21% clip. Unsurprisingly, it’s much more effective when he works it above the belt (.183 wOBA, 26% whiffs).
Baez’s changeup sits at 86 mph with some good fade. It doesn’t drop as much as you’d expect, but still missed bats at a 28% clip in 2019. Baez peppers the arm-side of the plate with this pitch, mostly using it against lefties.
Like the curveball, Baez throws his slider sparingly. The only real difference between the two pitches is the velocity: The slider comes in at 85 mph rather than 78 mph. The break here isn’t very tight and it’s probably best used as a show-me pitch rather than a weapon.
Baez doesn’t throw many curves (3%), which is probably a good plan for him. The pitch sits at 78 mph with below-average spin and movement. It just kind of loops in there. This pitch needs some work.
