The Twins lost their 11th straight game and have dropped 16 out of 17. The late-season swoon has brought Minnesota within five losses of 100, something the franchise has not suffered through in 29 years.
Minnesota starter Kevin Slowey (0-7) did not allow a hit through 5 2/3 innings, but gave up run-scoring doubles in the sixth to Kyle Seager and Dustin Ackley that rallied the Mariners from a 2-0 deficit. Seattle moved in front an inning later.
Justin Smoak opened the seventh with a single and went to second on a single by Miguel Olivo, and both runners moved up on a sacrifice by Adam Kennedy. Robinson came through with his two-out single that broke the tie and he then scored on a double by Ichiro Suzuki.
Cesar Jimenez (1-0) earned his first major league win in his third season with 1 1/3 innings of relief. Brandon League gave up a run on three hits in the ninth, but still collected his 36th save.
