NEW YORK -- Right-hander Daniel Mengden joined the A's in Cleveland on Monday to start the opener of a four-game series at Progressive Field, pitching in place of Kendall Graveman, who was placed on the 10-day disabled list, retroactive to Friday, with a right shoulder strain.
Graveman is dealing with right shoulder soreness for the second time this season and is expected to be sidelined longer than his first DL stint, which spanned April 15-26.
The A's Opening Night starter will be shut down for the time being, and there's no telling when he'll begin throwing again.
