The Oakland A's surprising run at an American League West title or AL wild-card berth has suffered a setback. Left-hander Brett Anderson has been ruled out for the season with a Grade 2 oblique strain.
The injury, suffered when Anderson awkwardly fell off the mound, forced Anderson to cut his Wednesday start against the Detroit Tigers short. The A's received his MRI result before today's 12-4 win over the Tigers. Anderson was 4-2 with a 2.57 ERA in six games and five starts for the A's.
Oakland has scheduled rookie Dan Straily to take Anderson's place in the rotation. His next start will be Monday's series opener against Texas. The four-game series in Arlington will have a direct impact on the tight Rangers-A's race. The Rangers begin tonight's game against the Los Angeles Angels in Anaheim with a 3-game lead in the AL West.
