CHICAGO -- Justin Steele will rejoin the Chicago Cubs' rotation Wednesday against Oakland.
Steele, Chicago's Opening Day starter, has been on the 15-day injured list since Sept. 1 with left elbow tendinitis. He is 5-5 with a 3.09 ERA in 22 starts this season.
The 29-year-old Steele had a bullpen session Saturday.
Right-hander Daniel Palencia was recalled from Triple-A Iowa before the matchup with the A's, and righty Trey Wingenter was sent down.
Steele last pitched Aug. 27 at Pittsburgh, allowing two runs in five innings in a 9-5 victory over the Pirates.
He had a breakout 2023 season, making the National League All-Star team while going 16-5 with a 3.06 ERA in 30 starts. He also struck out 176 in 173 innings.
Steele strained his left hamstring during his season-opening start at Texas on March 28. He didn't return until May 6 and scuffled for several weeks before getting on track.
