The Philadelphia Phillies will activate right-handed relief pitcher Orion Kerkering from the injured list ahead of their three-game series against the San Francisco Giants. Kerkering, one of the Phillies' top relievers, has been sidelined with a hamstring injury but is set to rejoin the team's bullpen for the crucial NL matchup.

Why it matters

The Phillies have struggled to win series in San Francisco in recent years, and the return of Kerkering, who had a strong 2022 season, could provide a boost to their relief corps as they look to turn that trend around against the Giants.

The details

Kerkering made one appearance this spring before suffering the hamstring injury, allowing two hits, an earned run, and a strikeout in one inning. He has been rehabbing with the Phillies' Triple-A affiliate, the Lehigh Valley IronPigs, where he posted a 2.25 ERA with five strikeouts in 4.0 innings. The 25-year-old right-hander went 8-4 with a 3.30 ERA, four saves, and 65 strikeouts in 60.0 innings for the Phillies last season.

  • Kerkering will be officially activated to the Phillies' roster on Tuesday, April 7, 2026, ahead of the series opener against the Giants.
  • The Phillies and Giants will play a three-game series from April 7-9, 2026 in San Francisco.

What they’re saying

“Even though Kerkering's blunder in the National League Divisional Series against the Los Angeles Dodgers — throwing the ball to catcher J.T. Realmuto at home with two outs instead of first base — Kerkering has proven to be one of the Phillies' better relievers.”

— Matt Gelb, Reporter

What’s next

The Phillies will monitor Kerkering's performance in his first few appearances back from the injured list to ensure he is fully recovered and ready to contribute to the bullpen for the remainder of the season.

The takeaway

Kerkering's return is a significant boost for the Phillies as they look to end their long drought of series wins in San Francisco. His proven track record as a reliable and effective reliever should provide a lift to the team's bullpen as they aim to take the series against the Giants.
