DETROIT (AP) - Prince Fielder had three hits and scored the tiebreaking run in the seventh inning on a close play at the plate, leading the Detroit Tigers over the Seattle Mariners 5-4 on Thursday. Detroit trailed 4-3 after Seattle's Dustin Ackley hit a three-run homer in the fifth, but Fielder's RBI single in the seventh tied it. Then he scored from first when Victor Martinez doubled off Charlie Furbush. It was a busy day for Fielder, who appeared to take and eat a fan's nacho after unsuccessfully chasing a fifth-inning foul ball near the stands. Torii Hunter homered for the Tigers. Doug Fister struck out 10 in 7 2-3 innings. Drew Smyly got one out, and Joaquin Benoit pitched a perfect ninth for his 22nd save in 22 chances.
