Right-hander Brandon Bielak recently underwent season-ending surgery, reports MLBTR’s Steve Adams. He’s expected to be ready for 2026 Spring Training. Bielak was released from a minor league deal with the Diamondbacks on Saturday after going on the full-season injured list last month.
The injury essentially ended Bielak’s stint with Arizona before it got off the ground. The 29-year-old signed a minor league contract with the Snakes in February. He worked 5 2/3 frames of two-run ball during Spring Training before being reassigned to the minors. Bielak started twice for Triple-A Reno. He allowed three runs across 9 2/3 innings with five strikeouts and walks apiece. Both appearances came within the first week of April. Bielak landed on the injured list on April 9 and was ruled out for the season within three days.
There’s a decent chance Bielak will spend the rest of the year as a free agent. He’ll be limited to minor league offers next winter but would again project as rotation or long relief depth if his recovery goes as expected. A former 11th-round draftee by the Astros, Bielak has spent most of his minor league career as a starting pitcher. He made 13 big league starts with Houston a couple seasons ago, though his 16 MLB appearances last year all came in relief.
Bielak divided last season between Houston and the A’s. He turned in a 5.16 ERA over 29 2/3 big league frames and a 6.08 mark across 16 Triple-A appearances. He now owns a 4.63 ERA over 204 major league innings. Bielak has a 4.37 mark over six career Triple-A seasons — a decent number for a depth starter who has spent all that time in the hitter-friendly Pacific Coast League.
