Mets News and Notes:Leading off: Jonathon Niese has been diagnosed with a partially torn rotator cuff, although surgery is not immediately being recommended, assistant general manager John Ricco said.
The diagnosis came after Niese was examined by team doctor David Altchek on Friday at the Hospital for Special Surgery in Manhattan. The southpaw landed on the disabled list Friday.
The Mets called up submariner Greg Burke to take Niese's roster spot.
Ricco said Niese will rest and undergo physical therapy for the next two weeks, after which he will have another MRI and revisit Altchek.
"Hopefully it will start healing itself and he won't need surgery," Ricco said. "But we'll know more after a couple of weeks of rest. According to the doctors, it's a small enough tear that with rest ... they're hopeful it won't need surgery. It's not 'full thickness' or a significant tear at this point."
Niese had been battling what the team labeled as shoulder tendinitis for several weeks, even missing a start while avoiding the disabled list. But Ricco said the partial rotator cuff tear is a new injury that did not appear on an MRI at that time.
With the Mets' rotation now back to five starters, there is more clarity about when Zack Wheeler will pitch.
Wheeler's second major league start comes Tuesday at the Chicago White Sox. He then is scheduled to make his Citi Field debut on June 30 against the Washington Nationals.
Barring inclement weather, Wheeler's following two starts leading into the All-Star break should be on the road: July 5 at Milwaukee and July 10 at San Francisco. It was the Giants who traded Wheeler to the Mets.
Mets Assistant GM John Ricco acknowledged the Mets are soliciting trade offers for outfielder Collin Cowgill, who was designated for assignment after Tuesday's game in Atlanta.
The assistant GM added, though, that the Mets would try to get Cowgill through waivers and send him to Triple-A Las Vegas if they were unable to get a suitable deal rather than release Cowgill.
Cowgill can be in limbo for up to eight days before the Mets initiate the waiver process.
Cowgill, who was acquired from the Oakland Athletics last offseason for minor league infielder
Jefry Marte, hit .180 with two homers in 61 at-bats with the Mets.
Travis d'Arnaud's clearance to run has been limited so far to activity in a rehab pool that reduces the amount of weight being placed on his fractured left foot, assistant GM John Ricco said.
Ricco said d'Arnaud would be reevaluated in a couple of days before being cleared to proceed to land-based running. The assistant GM reiterated that the expectation is d'Arnaud will return to games this season.
D'Arnaud suffered the fracture of the first metatarsal when he was struck with a foul ball while catching for Triple-A Las Vegas on April 17.
