Martinez went 2-for-4 with a two-run homer in the Tigers' 7-4 loss against the Indians on Monday.
Martinez had been in a slump entering Monday, hitting .214/.303/.375 in his last 15 games. It was his 22nd home run of the year, a figure that is down significantly from the career high of 38 he set last year. But Martinez's .313 batting average is much improved, up from .282 in 2015.
