The southpaw pitched so well this season that he was compared to New York Mets super-ace Johan Santana.
The Dominican pitcher jumped up to Triple-A Lehigh Valley after starting the season in Double-A Reading. He combined for a minuscule 1.90 ERA and 0.89 WHIP in 11 games (seven starts).
The biggest draw to bringing the 23-year-old up now was his 5:1 K's to walk ratio.
He last took the mound Thursday night for the IronPigs. He allowed six hits and one walk over seven scoreless innings in the Pigs 7-1 win over Buffalo.
