The Indians have started to pull away in the AL Central and are now looking to fill some voids in the roster for their playoff push. The team is very sound in the infield and on the mound, but some more options in the outfield would do them some good.
The Tigers, meanwhile, are not realistically in contention and look ripe for some form of a rebuild. Even though they are division rivals, the two teams found a deal that works for both teams.
Leonys Martin has put together a strong season for the Tigers with a .251/.329/.40 line and strong outfield defense which has buoyed him to 1.8 rWAR on the season. Martin isn’t a game changer at this point in his career, but he does provide value in the field in particular.
In exchange, the Tigers got shortstop prospect Willi Castro who has a promising bat from both sides of the plate and currently sports a .653 OPS in Double-A and has swiped 13 bags in 2018.
