Zach Eflin Exits Start With Elbow Discomfort

Orioles righty Zach Eflin left his season debut tonight in the fourth inning after a visit from the trainers. The team announced the issue as elbow discomfort and will surely have more details over the next few days.

The injury seemingly occurred on a 76 mph curveball to Texas third baseman Ezequiel Duran. Eflin had pitched well before the injury, striking out seven while allowing one run across 3 2/3 frames. His velocity was fine throughout the appearance and there was no indication the veteran righty was struggling physically until his last pitch. Baltimore’s bullpen would give up seven runs over the final 4 1/3 innings and take an 8-5 loss.

Eflin has unfortunately battled a number of injuries throughout his career. Knee issues were the main concern during his early days with the Phillies. Over the past couple seasons, he had been bothered more frequently by back and arm issues. Eflin had brief injured list stints related to his lower back in both 2023 and ’24. He had three trips to the IL last year, a season in which he was limited to 14 starts.

The 31-year-old suffered a lat strain in April, knocking him out for a month. The back flared up not long after he returned. A second back injury resulted in a lumbar microdiscectomy that ended his season. Eflin returned to the O’s on a one-year, $10MM free agent deal midway through the rehab. That went without issue, but his return for the start of the season is clouded by possible concern about the elbow.

If Eflin hits the injured list, the O’s would presumably turn to Dean Kremer to round out the rotation. Baltimore optioned him to Triple-A to begin the season. It was a numbers game more than anything, as they would have needed to go to a six-man rotation if they didn’t want to use Kremer out of the bullpen. He’s a perfectly capable fifth starter who’d slot behind Trevor Rogers, Kyle Bradish, Shane Baz and Chris Bassitt.
