Green was recalled from Triple-A Scranton/Wilkes-Barre on Monday.
Green was added to provide a much-needed arm out of the bullpen for the Yankees, who depleted their relief corps during Sunday's 18-inning win over the Cubs. The 26-year-old owns a 4.72 ERA with 33 strikeouts through 26.2 innings (five starts) at Triple-A this season. Green will be available as a long-relief option, as he was scheduled to start with Scranton/Wilkes-Barre on Monday.
