Cano had a sizable welt near his left temple after being struck in the dugout when an errant throw got past Angels first baseman Albert Pujols before the seventh inning.
Cano felt dizzy and was taken to the clubhouse, where the Mariners’ medical staff checked the second baseman for a concussion. No signs of one were found.
Garrett Richards (8-5) pitched into the eighth inning, Kole Calhoun hit a two-run homer and third baseman David Freese made a couple of key defensive plays.
Huston Street got three outs for his 21st save in 23 chances.
J.A. Happ (3-5) is 0-4 over his last four starts after five consecutive no-decisions.
