The Philadelphia Phillies' bullpen is set to get a boost with the impending return of right-handed reliever Orion Kerkering. After pitching one more game for the team's Triple-A affiliate Lehigh Valley on Saturday, Kerkering will join the major league roster in San Francisco.

Why it matters

  • Kerkering will pitch one more time for Triple-A Lehigh Valley on Saturday, April 5, 2026.
  • Kerkering will then join the Phillies in San Francisco on April 6, 2026.
