The Yankees recalled Ramirez from Triple-A Scranton/Wilkes-Barre on Saturday.
With Ryan Weber (forearm) headed for the injured list, Ramirez will return to the Yankees' bullpen in his place. The 33-year-old lefty holds a 2.00 ERA and 1.33 WHIP through nine big-league innings this season, but his 5:4 K:BB ratio makes it unlikely he sees many high-leverage situations.
