The Oakland A's jumped out to an early lead Thursday night, but a two-inning, 10-run spurt by the Texas Rangers turned the tables quickly and sent the A's to their fourth loss in five games, 11-3 at the Coliseum.
Danny Santana hit a grand slam and drove in a career-high six runs for the slumping Rangers.
Asdrubal Cabrera had three hits and scored twice. Shin-Soo Choo and Delino DeShields added two hits apiece during the Rangers' highest-scoring game in nearly seven weeks.
Texas won after placing outfielder Joey Gallo on the injured list following wrist surgery earlier in the day. The All-Star slugger will miss at least a month.
Santana fell a triple shy of hitting for the cycle while helping the Rangers to only their second win in 11 games. He singled in the first inning and had a two-run double as part of a five-run fifth against A's starter Brett Anderson.
Santana homered with the bases loaded in the sixth off reliever Wei-Chung Wang. He struck out swinging in the eighth in his final at-bat.
Ramon Laureano singled in two runs for Oakland. The A's have lost four of five and hold a half-game lead for the second AL wild card.
Ariel Jurado (6-6) overcame a shaky start and allowed three runs on three hits in seven innings for his first win since June 27. Jurado struck out six, walked two and retired 16 of the final 17 batters he faced.
Anderson (9-6) gave up five runs in 4 2/3 innings. The left-hander was activated from the paternity list before the game.
