Dillon Dingler hit his first career home run, Matt Vierling also went deep, and the Detroit Tigers held on to beat the San Francisco Giants 5-4 on Sunday to avoid the three-game series sweep. Colt Keith added two hits and an RBI and three Tigers relievers combined for four shutout innings to back rookie Keider Montero's uneven outing. Dingler hit a two-run home run in the second inning then doubled and scored in the fifth.
