Kopech won't start as scheduled Saturday and will instead move into a multi-inning relief role, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

After putting up a 9.50 ERA and 2.33 WHIP through 18 frames across his last five starts, Kopech will officially lose his spot in the rotation. The team reportedly still views him as a starter for next season, but a few good appearances out of the bullpen to close out 2023 would help Kopech build his case. Jose Urena will be selected from Triple-A Charlotte to start in Kopech's place Saturday against the Tigers.
