Baltimore Orioles pitcher Zach Eflin has undergone successful Tommy John surgery, sidelining him for the remainder of the 2026 season. Eflin, the team's Opening Day starter last year, made just one start this season before exiting with right elbow discomfort. The Orioles' pitching rotation has now been significantly impacted, with several other pitchers also on the injured list.

Why it matters

The loss of Eflin is a major blow to the Orioles' starting rotation, which the team had worked to bolster in the offseason. With several other pitchers already on the IL, the Orioles' depth is being severely tested early in the season, raising concerns about their ability to remain competitive in the AL East.

The details

Eflin was removed from his first start of the season against the Texas Rangers after just 3.2 innings. He had struck out seven batters but also allowed a solo home run. After being placed on the 60-day IL, Eflin sought a second opinion and underwent Tommy John surgery on Wednesday. The 32-year-old's season is now over, and his status with the Orioles in 2027 is uncertain.

  • Eflin made his first start of the 2026 season on April 7.
  • Eflin was placed on the 60-day IL earlier this week.
  • Eflin underwent successful Tommy John surgery on April 12.
