According to research on baseball-reference.com, Jackson's 10th triple made him just the fifth Tigers player with at least 20 doubles, 10 triples, 10 home runs and 10 stolen bases in multiple seasons. He's just the fourth Tiger to do it in back-to-back years.
Curtis Granderson did it in 2007-08, Charlie Gehringer in 1929-30, and Bobby Veach in 1920-21. Ty Cobb hit the marks in 1921 and 1925.
Just three players besides Jackson and Granderson have done it even once over the past 30 years. Carlos Guillen got there in his first season with the Tigers in 2004. Kirk Gibson made it in 1984, two years after Larry Herndon did.
Jackson's triple also extended his American League lead by two over Oakland's Jemile Weeks, who's currently finishing up the season at Triple-A Sacramento, and three over Chicago's Alex Rios. If Jackson holds on, he'll join Granderson (2007-08) as the two Tigers to lead the league in triples in back-to-back seasons since Cobb in 1917-18. Jackson shared last year's crown with Angels speedster Peter Bourjos.
Granderson's big boost in triples came in 2007, after Tigers baserunning coach Andy Van Slyke tried to get him to be more aggressive and think extra bases on contact rather than rounding second base. Jackson doesn't take quite the same approach.
"Sometimes I'm running hard enough where I'm looking up close to second base and they're still running after the ball," Jackson said.
