At first glance it appears that the Tigers gave up far to much for only Shane Greene, but upon deeper look at Shane Greene I reached the conclusion that they might be the winners in this trade. Shane Greene was drafted by the Yankees soon after he had finished rehab from Tommy John surgery. The hard work done in rehab allowed Greene to improve after the surgery and after four years in the minors, including the 2013 season in which he won an award as the Yankees best minor league pitcher, Greene made his debut April 24th 2014. In Greene's 78 and 2/3 inning in 2014, he had as many strikeouts as hits allowed (81) and more than half the balls batters did put in play were ground balls. Greene's promising career is just getting started, he only just turned 26. Greene may also be a crucial part of the Tigers rotation that allows them to move Porcello for Cespedes as some rumors indicate could happen.
The Diamondbacks gave up Didi Gregorious for two prospects from the Tigers, Robbie Ray and Domingo Leyba. The D-Backs made the riskiest move of the three teams because Robbie Ray has struggled so far in his short time in the majors, and Leyba is too young to know for sure what will happen, but as usual when dealing prospects if they turn out, this deal could be very beneficial for the D-Backs.
