Mize is slated to make his spring training debut Saturday against the Pirates, Evan Woodbery of MLive.com reports.
Offseason addition Eduardo Rodriguez will kick off the team's spring schedule Friday, followed by Mize on Saturday. The latter took a step forward in 2021, posting a 3.71 ERA after registering a 6.99 ERA as a rookie in the condensed 2020 season. Mize will turn 25 this year and should just be hitting his stride as a top-of-the-rotation pitcher, though he'll likely need to miss more bats to really take off. He struck out only 118 batters across 150.1 innings last year.
