Brandon Cumpton was drafted in the 9th round of the 2010 draft, the same draft that grabbed other top prospects Jameson Taillon, Stetson Allie, and Nick Kingham. Cumpton made his MLB debut last year on June 15, 2013 getting a no decision in his career debut despite striking out 5 of the first 6 batters he faced. He's currently 2-2 over his career with a 2.70 ERA over 43.1 innings pitched with a 5.17 K/BB rate.
Many people aren't giving Cumpton the respect that he deserves, citing that he will likely never be more than a spot starter. From what I have seen of Brandon so far in his early career, he likely has the opportunity to be a middle rotation innings eater.
The Pirates have faced several early season pitching injuries and ineffectiveness so I wouldn't be surprised if he is able to gain a permanent spot in the rotation by midseason.
I purchased the above card for $6 off ebay and plan on grabbing a few of his 2014 Bowman variants when prices start to drop.
