The Tigers split the series against the Mariners and entered Monday holding a half-game lead over the Cleveland Indians in the American League Central.
On the year, Granderson is hitting .293 with 13 home runs, 45 RBIs, 69 runs and 10 stolen bases. The 26-year-old has been a catalyst for the Tigers the entire season with his league-leading 55 extra-base hits, four shy of his total last season.
Granderson was "stumped" as to how he is ahead of Alex Rodriguez, Magglio Ordonez, Alex Rios and David Ortiz in extra-base hits. The last Tiger to lead the league in extra-base hits was Cecil Fielder, who did it in 1990 with 51 home runs, 25 doubles and a triple.
"There is a long way to go, and the hitters that are surrounding me are going to make a push," Granderson told the Detroit Free Press recently. "It's definitely going to be tough."
Manger Jim Leyland told the Free Press, "He's missing fewer pitches that he can hit. He's hitting them more often."
Granderson also leads the league in triples with 16, his last coming Saturday. He is on pace to break the Tigers' all-time triples record of 26, set by "Wahoo" Sam Crawford in 1914.
Tourneau, the world's largest watch store, will supply Granderson with an engraved timepiece recognizing his achievement.
