A's place McCarthy, Ross on disabled list
The Oakland Athletics have placed right-handers Brandon McCarthy and Tyson Ross on the 15-day disabled list in the latest injury-related moves for their rotation.
The A's also optioned reliever Trystan Magnuson to Triple-A Sacramento on Friday. Right-handers Joey Devine and Fautino De Los Santos and lefty Jerry Blevins were recalled from Sacramento.
McCarthy has a stress reaction in his throwing shoulder that has sidelined him in the past. Ross left Thursday's game against the Minnesota Twins with a strained left side after throwing seven pitches.
Ross had taken the spot in the rotation vacated by lefty Dallas Braden, who had season-ending shoulder surgery earlier this week.
Oakland was playing at the San Francisco Giants on Friday night.
