Casilla’s two-seam saw a dip in zone rate of about nine percent in 2018, which bumped his walk rate up to over 14% on the pitch. With a drop in velocity of over one mph, Casilla skated by with a lucky .250 BABIP on the two-seamer. Casilla should continue to decrease the usage of the two-seam fastball going forward.

Casilla’s primary offspeed pitch saw gains in usage by 7% and in vertical drop by 1.5 inches, which helped to increase his ground-ball rate to over 70% on the pitch. The knuckle-curve resulted in a 32.5% strikeout rate. At this stage in his career, Casilla should continue to throw his secondaries more often.

Casilla lost a tick on his four-seam which contributed to a decrease in strikeouts. A low BABIP and suppression of home runs allowed the four-seam to succeed despite seeing the contact rates go up. Casilla will need to continue to tweak his pitch mix in order to continue his success.

The slider was not a major part of Casilla’s arsenal in 2018. Casilla may have lost the feel for the pitch, as the zone rate dropped by seven percent. In addition, the chase rate dropped below 20% and the swing strike rate was down to 8.9%. Casilla should reduce the usage of the slider in favor of the curveball.

Casilla rarely uses his changeup in his arsenal. In 2018, Casilla struggled to throw the pitch inside the zone more than 20% of the time. Casilla should eliminate this pitch as it failed to fool many hitters, inducing only 15.4% swings outside the zone.
