For the third time in 2026, the Chicago Cubs placed right-handed reliever Phil Maton on the 15-day injured list on Monday due to continuing struggles with right knee tendinitis.
Manager Craig Counsell told reporters before the series opener vs. Detroit that Maton, 33, underwent an MRI and the results were not encouraging.
“We were all optimistic,” Counsell said of Maton’s return to action against Minnesota on Sunday. “He thought, we thought, we were in a pretty good place. … We’re looking at a little bit more extended absence here.”
Maton threw 23 pitches in the eighth inning of the 10-1 victory over the Twins. He hit the strike zone 19 times, but did allow one run, two hits and a walk.
But the 10-year veteran felt a flare-up of the right knee symptoms, according to Counsell.
Maton had last pitched on June 25 and was activated from the 15-day IL on July 11.
He made five appearances in March and April before hitting the injured list for the first time after an April 7 outing in Tampa Bay.
Maton, who pitched to a 2.79 ERA with the Cardinals and Rangers in 2025, signed a two-year, $14.5 million contract this winter to serve in a high-leverage capacity for the Cubs.
In 31 games this season, he is 0-1 with a 6.18 ERA and 1.81 WHIP, fanning 31 batters and walking 16 walks in 27 2/3 innings.
The Cubs added Aaron Civale (5-7, 5.42 ERA) to the roster on Monday after acquiring him on Athletics on Saturday.
In addition, Chicago activated Jameson Taillon (hamstring) from the injured list and he made the start against the Tigers on Monday. Taillon pitched 4 1/3 innings and allowed four runs on five hits, walking two and fanning six.
To make room for Taillon, the Cubs designated left-handed reliever Drew Pomeranz for assignment.
