• Jacob deGrom (right rotator cuff tendinitis) is expected to throw for the first time on Saturday. The Mets originally expected the rookie right-hander to miss just two starts -- putting him on track to start sometime next weekend -- but manager Terry Collins doesn't know if that is still the case.
"Is he going to come off [the disabled list] in time? History would say yeah, probably, due to the issue he had," Collins said. "He may not. I have no idea."
• Ruben Tejada, who has not started in a game in over a week since the Mets named Wilmer Flores their No. 1 shortstop, will start a game against the Cubs this weekend.
"He's got to get out there," Collins said. "Wilmer's played a week straight now, there's no reason he can't have a day [off] here and there."
• The Mets formally released outfielder Chris Young on Friday. Young was designated for assignment Aug. 9.
