DETROIT — The Tigers finalized a $68 million, four-year deal with Victor Martinez, keeping the slugging designated hitter in the middle of Detriot's lineup after he finished second in the AL MVP race this year.

Martinez hit .335 with 32 home runs and 103 RBIs, helping Detroit to its fourth straight AL Central title. Detroit agreed to the lucrative deal less than six weeks before Martinez's 36th birthday, showing the Tigers still are willing to spend big in pursuit of their first World Series championship since 1984.

The switch-hitting Martinez has batted over .300 in eight of his last nine seasons, not counting 2012, when he missed the whole season with a knee injury. His bat carried the Tigers at times in 2014.
