Gallegos was recalled from Triple-A Scranton/Wilkes-Barre on Thursday.
Gallegos was sent back to Triple-A to start the season, but it comes as no surprise that he's headed to the big leagues after fanning 26 batters in just 14 innings pitched. He did walk six in that span and currently holds a 3.86 ERA, but he'll look to improve upon that as he presumably enters a middle-relief role in the Yankees' bullpen.
