Gallegos was optioned to Triple-A Scranton/Wilkes-Barre following Saturday's contest, Coley Harvey of ESPN.com repots.
Before his demotion, Gallegos chewed up two innings in the 11-0 loss to Boston. The Yankees might need to promote a catcher with Austin Romine (hamstring) injured, and the mop-up righty was a logical subtraction to free up a roster space. Though his ERA shot up from 0.00 to 3.86 as he gave up three runs Saturday, he's quietly impressed with 10 strikeouts and just one walk over his seven major-league innings. He might have a return ticket on the shuttle for the next time the team needs to fill a bullpen void.
