The fastball isn’t much to write home about, but it’s serviceable. It sits 93-94 and has a little armside action to it. It was hit hard in 2019 (.813 wOBA!) and it would be best if Avila was more selective on when and where he threw it.
Avila’s curveball has some nice, big bend to it. It sits at about 74 mph and he breaks it off about a quarter of the time. It looks similar to the slider, but has definitively more drop to it. Might work better for him if he buried it more rather than dropping it in the zone.
