Boesch goes 0-for-3 in Yankees' 7-0 loss to the Phillies
New York agreed to a one-year contract with Boesch on Friday. The Yankees will be without outfielder Curtis Granderson until at least May due to a broken right forearm.
Domonic Brown hit his fourth spring training homer, a three-drive in a four-run fourth against Hiroki Kuroda, who allowed four runs - two earned - and six hits in six innings.
Philadelphia opening-day starter Cole Hamels didn't make the trip and instead pitched in a minor league intrasquad game, where he gave up four earned runs and six hits over five innings during an 84-pitch outing.
