Tanaka is the third member of the Yankees’ primary starting five to go down over the past month and the second in the past two days. Michael Pineda was placed on the disabled list and had Tommy John surgery immediately following the All-Star break, and CC Sabathia went on the DL with right knee inflammation on Friday.
The Yankees acquired right-hander Sonny Gray and lefty Jaime Garcia at the trade deadline to bolster their rotation, and considering the injuries that have since occurred, those both look like great moves. Rookie Jordan Montgomery, who has started 21 big-league games this season, was recalled from Triple-A Scranton-Wilkes Barre on Friday to fill Sabathia’s spot after being demoted last week, but now his status is also up in the air, as he was struck in the head with a ball during batting practice on Saturday according to FOX’s Ken Rosenthal.
Tanaka is expected to return rather quickly, but in the meantime, candidates to fill his rotation spot include Bryan Mitchell, Luis Cessa, and Chance Adams.
