The Yankees optioned Bird to Triple-A Scranton/Wilkes-Barre on Sunday.
After allowing five earned runs in one-third of an inning in the Yankees' 8-2 loss in the first game of Sunday's doubleheader with the Dodgers, Bird was sent down to Triple-A in advance of Game 2. The Yankees will swap Bird off the 26-man active roster for a fresh bullpen arm in Kervin Castro, who was recalled from Scranton/Wilkes-Barre in a corresponding move.
