NEW YORK — Yankees left-hander CC Sabatthia was put on the 10-day disabled list because of right knee inflammation and left-hander Jordan Montgomery was recalled from Triple-A Scranton/Wilkes-Barre.
New York also activated infielder Tyler Austin from the 10-day disabled list before Friday's game against Boston and optioned him to Scranton.
Sabathia's move was retroactive to Wednesday, a day after he allowed four runs in three innings at Toronto and left in pain. He is 9-5 with a 4.05 ERA in 19 starts, pitching with a brace because of the knee.
Montgomery, 7-6 with a 4.05 ERA in 21 starts, figures to take Sabathia's turn Sunday against the Red Sox.
