It’s strange, I know, to place the Rays among those who may be looking to add a veteran pitcher like Jose Quintana. The prominent lefty has been a 3.5 WAR or better pitcher since 2013, reaching a high of 5.1 WAR in 2014 and 4.8 WAR in both 2015 and 2016. To put that into perspective, it made him the 10th most valuable SP in terms of WAR for 2016.
Overall, his statistics speak for themselves; you can have a glance here if you’d like to brush up on how impressive they actually are.
