3. J.D. Martinez, 2015 (102)
It seems like J.D. Martinez just got better once he left Detroit, but he was still pretty darn good wearing the Old English D. His 2015 season was arguably his best, since that's the only year he played a full season with the Tigers.
He hit 38 home runs and was worth 5.2 fWAR, which is the second-highest of his career to this point. He was one heck of a find by Dave Dombrowski.
Most Tigers fans will think of the pinch-hit home run he hit off Chris Sale in 2016 after coming off the IL when they think of J.D. Martinez, but he was much more than that one homer. He was so good with the Tigers. He just came up right at the end of their run. It would be interesting to see what would have happened had the Astros let him go even just one year earlier and he fixed his swing then.
