3. J.D. Martinez, 2015 (38)
Just Dingers is what they called him. J.D. Martinez was a heck of a find by Dave Dombrowski. As soon as he was cut by the Astros, he fixed his swing and signed with the Tigers on a minor league deal.
After hitting 10 homers in 17 games in Toledo, the Tigers called him up, and the rest was history.
J.D.'s 38-homer campaign in 2015 was one of the few highlights of that season. The Tigers massively disappointed with a 74-87 record, but he just did his thing and raked.
Way too many people just remember the subpar return the Tigers got when they traded him to Arizona in 2017, completely forgetting how good he was. J.D. Martinez was one of the best hitters the Tigers have had in recent memory.
