Switch-hitting utilityman Marwin Gonzalez will play a key role off the shortened bench.
"Marwin's versatility gives up pretty good coverage everywhere," Boone said before an exhibition Tuesday against the Detroit Tigers. "Just early on, got to make sure we protect and build up the arms properly. We'll make it work, and if we have to change on the fly a little bit, we'll do that."
Teams are allowed to carry 28 players during April due to the shortened spring training.
Boone said the Yankees are planning to return to 13 pitchers and four position reserves when the expanded rosters end May 1.
Bird is back
The Yankees signed first baseman Greg Bird to a minor league contract and assigned him to Triple-A Scranton/Wilkes-Barre. Bird was with New York from 2015 to 2019 but had his career derailed by injuries. He opted out of his contract with the Toronto Blue Jays after hitting .261 with two homers and six RBIs during spring training,
Bird, 29, played in Triple-A for Colorado last season, hitting .267 with 27 home runs and 91 RBIs.
"He can hit," Boone said. "Health has always been the issue for him, but I don't think anyone has ever doubted his potential and what he could be as a big league hitter. Get another talented guy that appears to be healthy."
