The Philadelphia Phillies finally have an explanation for Orion Kerkering’s week-long absence from the mound, and the reliever has been dealing with inflammation in his left big toe.
Interim manager Don Mattingly told reporters that Kerkering has not pitched in a week but was available during Friday’s 6-5 loss to the Atlanta Braves. Tim Kelly of Phillies Nation reported on X that Kerkering has been wearing a walking boot on his left foot away from the ballpark as a precaution.
The Phillies did not turn to Kerkering during Friday’s extra-inning loss despite the right-hander being available.
Orion Kerkering is dealing with inflammation in his left big toe. He hasn’t pitched in a week, but was available tonight, per Don Mattingly. For precaution, he has a boot on his left foot away from the park.

Kerkering’s absence has been noticeable as Philadelphia manages its bullpen during a critical stretch of the season. The reliever has also dealt with a difficult second half, making his return to a regular high-leverage role more complicated.
Before the All-Star break, Kerkering held opposing hitters to a .172 batting average over his first 37 innings. His results have declined since then, with his ERA climbing to 7.64 after the break.
His last appearance came Sept. 4 against Atlanta, when he allowed a two-run homer to Mauricio Dubón. Mattingly had already indicated that Kerkering’s role would be reduced to lower-leverage situations following his recent struggles.
The toe issue now provides additional context for why Philadelphia has been cautious with the young reliever. Although Mattingly said Kerkering was available Friday, the walking boot suggests the Phillies are still taking the inflammation seriously.
Philadelphia ultimately fell to Atlanta in 11 innings, with the Braves improving to 87-61 and extending their NL East lead to five games over the Phillies.
With only 14 games remaining, the Phillies will need as much bullpen depth as possible. Getting Kerkering healthy and back on the mound could give Mattingly another option as Philadelphia prepares for the final stretch.
