Cespedes was injured running the bases in the first inning Friday night. General manager Sandy Alderson said Cespedes’ “season is in jeopardy.”
The 31-year-old has been limited to 81 games this season because of various injuries. He’s hitting .292 with 17 home runs and 42 RBIs for a team that has fallen out of playoff contention.
Reyes had been on the DL since mid-August with a sore left ribcage. He’s hitting .223 with nine home runs and 39 RBIs.
New York on Saturday also called up outfielder Travis Taijeron from Triple-A Las Vegas and optioned right-hander Kevin McGowan.
