Up on taxi squad
PBaltimore Orioles
April 8, 2025
According to Matt Weyrich of The Baltimore Sun, Selby joined the Orioles as a member of the taxi squad ahead of Tuesday's game against the Diamondbacks.
Analysis
Zach Eflin departed Monday's start due to right shoulder fatigue, so Baltimore elected to bring in some pitching depth for the tail end of the road trip. Selby has allowed just one hit in 3.1 scoreless frames in three relief appearances for Triple-A Norfolk this season.
