Mariners' Bradley leaves with back spasms

Mariners' left fielder Milton Bradley has left Friday night's game against Oakland in the third inning because of lower back spasms.

Bradley played the first two innings and walked in his only at-bat before he was replaced by Michael Saunders before the top of the third.

Bradley also missed Thursday's series opener against the A's after not feeling well. He entered Friday hitting .250 with a team-high 10 RBIs.
