## Pitching style

Joaquín throws three pitches: a fastball, a slider, and a changeup. The fastball travels 94 miles per hour (151 km/h) to 98 miles per hour (158 km/h) and travels quickly to the upper inside corner of the strike zone for right-handed batters. Left-handed batters can see it more easily. The slider travels in the middle 80 miles per hour (130 km/h) range. Sam Corun of Bleacher Report mentioned in 2010 that his changeup needed to be better in order for him to walk fewer hitters.
