Jacob deGrom will start throwing again when swelling subsides in his shoulder, which will hopefully be in the next five to six days, Terry Collins said Tuesday.
DeGrom was recently placed on the disabled list with rotator cuff tendinitis.
He told reporters Tuesday that he hoped to only miss two starts.
“I feel like I’ve been in good shape,” he said. “I hadn’t felt anything until now.”
Mets pitching prospect Rafael Montero has been promoted from Triple-A to start in deGrom’s place Tuesday against the Nationals.
DeGrom, who was named MLB’s Rookie of the Month in July, is 6-5 with a 2.87 ERA in 16 starts for the Mets this season.
Montero, who was recently named Pitchers of the Week for his league in Triple-A, was 0-2 with a 5.40 ERA, including 17 strike outs in 20 innings, spanning four starts earlier this season for the Mets.
