Kolarek dramatically shifted his pitching arsenal for the second season in a row, this time introducing an 89.26 mph sinker. It essentially replaced his four seam fastball with a 70.7%/10.6% split, and it helped him induce a 66.3% ground-ball rate. However, he lost his magic touch from 2018 when he didn’t give up a single home run the entire season, jumping up to a 1.15 HR/9 rate.
