Former Rays Prospect Debuts With Padres
The Tampa Bay Rays drafted Jesse Hahn in the sixth round of the 2010 draft out of Virginia Polytechnic Institute and State University. In his last start in college he lasted only three innings before feeling a sharp pain in his elbow. An MRI revealed that he had torn the Ulnar Collateral Ligament (UCL) and required Tommy John Surgery.
The hard throwing (fastball which reaches 95 mph) right hander finally made it back to the mound for the Rays in 2012 and had his workload monitored appearing in 14 games and tossing only 52 innings. The kid gloves were not taken off in 2013 as he appeared in 20 games and only worked 69 innings.
He began the year with the Padres Double-A affiliate San Antonio Missions where he appeared in 10 games (seven starts) and posted a 2-1 record with an ERA of 2.20.
The Padres were in need of a starter and since Hahn is on their 40-man roster they dipped into their system and tapped him to make his major league debut.
His outing was less than impressive as he lasted only 3.2 innings giving up four runs (all earned) on six hits including two home runs (Neil Walker  and Pedro Alvarez ) striking out five and walking two.
Although the Padres bullpen held the Pirates at bay the remainder of the game the Padres offense was unable to come back and Hahn was tagged for his first major league loss.
