The White Sox are moving starter Michael Kopech to a bullpen role to begin the 2024 season, general manager Chris Getz announced to reporters on Thursday (X link via Sox Machine’s James Fegan). That’ll further shake up a rotation that suddenly projects to look quite different following last night’s trade sending Dylan Cease to San Diego.
Kopech was once a highly-touted prospect but has struggled to establish himself as a viable big league starter and is now on the cusp of his 28th birthday. Selected by the Red Sox with the 33rd overall pick in 2014, he was a top 100 prospect as he worked his way up the minor league ladder and was a key piece of the 2016 trade that sent Chris Sale to Boston.
The White Sox were surely hoping that Kopech would be a building block of their future rotation and promoted Kopech in August of 2018, but he required Tommy John surgery just about a month later. He missed all of the 2019 season and then sat out the 2020 pandemic season as well. After missing two full years of his development, he pitched primarily in relief in 2021 to build up his workload. He tossed 69 1/3 innings over 44 appearances that year with a solid 3.50 earned run average.
In 2022, he was finally able to secure a rotation gig at the big league level and the results were mixed. On the surface, his 3.54 ERA over 25 starts looked nice, but the numbers under the hood were less encouraging. His 21.3% strikeout rate and 11.5% walk rate were both a bit worse than league average. He seemed to have had some luck keeping runs off the board thanks to a .223 batting average on balls in play and 74.2% strand rate. His 4.50 FIP and 4.73 SIERA suggested that he may not have been as effective as his ERA implied.
Last year, his luck turned for the worse, as he finished the season with a 5.43 ERA. His control took a concerning blow, as he gave out walks to 15.4% of opponents. He was bumped to the bullpen late in the year but seemed like he had a path to continue starting in 2024. The Sox traded Lance Lynn and Lucas Giolito at the deadline last year and then saw Mike Clevinger hit free agency coming into this winter. Rumors swirled around Dylan Cease all winter until he was finally traded to the Padres yesterday.
Despite all of those holes in the rotation, it seems the Sox don’t have much faith in Kopech as a starter at the moment and he’ll wind up in the bullpen. For what it’s worth, he’s allowed six earned run in seven innings this spring, giving out six walks in the process while also hitting two batters. He’s now just two years away from becoming a free agent so perhaps the Sox will give rotation opportunities to younger guys during their current teardown, while perhaps Kopech can turn himself into a trade chip if he can serve as an effective reliever.
Kopech doesn’t seem thrilled with his new assignment. “It’s not my first choice where I want to be,” he said to reporters, including Scott Merkin of MLB.com. “I like starting, but I’ve had success in that role. And ultimately we are looking at what’s best for the team this year. If I can help us win games in the back of the game, I’m excited to do that.”
The Sox have brought in various fresh arms to the system this year, having signed Erick Fedde and Chris Flexen while also trading for Michael Soroka, Jared Shuster, Drew Thorpe and Jairo Iriarte. They got Jake Eder from the Marlins in last year’s Jake Burger trade. Garrett Crochet seems poised to move in the opposite direction to Kopech, jumping from a relief role into the rotation.
For now, the rotation projects to include Fedde, Flexen, Crochet and Soroka in four spots. The club was recently linked to free agent Michael Lorenzen and Clevinger as well, so a late signing could fill out the rotation. As the season rolls along, some guys will get hurt or may end up as trade targets at the deadline. Soroka and Flexen are impending free agents while Fedde is on a two-year deal. If Lorenzen or Clevinger sign, they would presumably be for one- or two-year deals.
As rotation spots open, perhaps Kopech could retake one, but the group of Shuster, Thorpe, Iriarte, Eder and others will be jockeying for auditions. With the club clearly focused on the future, they may be more inclined to give opportunities to those young and controllable guys as opposed to a 28-year-old whose club control is running out.
