Wednesday, 7:05 PM – Joe Kelly
Kelly throws from a low three-quarters arm slot. He lives on a hard sinker that shows off quite a bit of sharp arm-side run. The pitch sits 92-95 MPH and touches the 97-98 range at times. His primary secondary offering is a 79-82 MPH curve, which he has gone to regularly against right-handed batters early in his major league career. He also mixes in a 93-96 MPH four-seam fastball and an 82-87 MPH changeup. So far, the offspeed pitches have been his best swing-and-miss offerings at the big league level. Despite the plus velocity, opposing hitters have not had a ton of trouble putting his fastball in play. Kelly has generated a good number of ground balls with the heater, though.
