The Athletics have announced a series of roster moves involving their bullpen. Lefty Sean Doolittle has been placed on the 10-day DL with what the team is describing as a shoulder strain, while righty Cesar Valdez was designated for assignment.
Oakland will promote two righties to take the open roster spots. Bobby Wahl and Josh Smith are each headed to the majors for the first time this year — indeed, the first time ever in Wahl’s case.
It’s rough news for Doolittle, who has dealt with frequent arm issues in recent seasons but had been in fine form thus far.
