The Yankees optioned right-handed pitcher Scott Effross and infielder Jorbit Vivas to Triple-A Scranton/Wilkes-Barre after Friday's trade with the Colorado Rockies for third baseman Ryan McMahon.
Will McMahon play for New York in Saturday's 1:05 p.m. game against the Philadelphia Phillies?
"Yeah, I expect him available," Boone said after Friday's 12-5 loss.
The 31-year-old Effross threw 23 pitches (13) strikes and allowed four runs on four hits in one inning, the ninth, where the Phillies (59-44) put Friday's game out of reach. He has allowed 10 runs on 16 hits while striking out six and walking three in 10.2 innings pitched over 11 games.
Vivas, 24, entered Friday's game at third base in the eighth inning and flew out to right field for the ninth's second out. He is slashing .161/.266/.250 with one home run and five RBI through 29 games.
The 30-year-old McMahon, who was a 2024 All-Star, joins the Yankees (56-47) at a pivotal time. He does so with a .217/.314/.403 slash line, 16 home runs and 35 RBI through 100 games this season.
"He's a really good player, great defender," said first baseman Paul Goldschmidt. "… He's a good hitter, and he's going to help us."
