Mets P Harvey has partially torn UCL
New York Mets starting pitcher Matt Harvey has a partially torn ulnar collateral ligament and likely will be shut down for the rest of the season.
A determination on whether Harvey will need Tommy John surgery will be made later, according to the source.
"It was the last thing I was expecting when I went in this morning (for an MRI)," Harvey said. "I haven't had shooting pains down my hand or in my elbow. It mostly has been forearm tightness, something I can pitch through. This last start, it felt a little more uncomfortable than normal.
"I'm going to do everything I can so I don't have to get surgery."
Harvey went on to talk about strengthening his elbow and shoulder, as well as stretching. Mets general manager Sandy Alderson said swelling in the elbow must go down before a decision about surgery can be made. Alderson did not completely rule out Harvey pitching again this season, though he said that's unlikely.
Harvey managed to throw 102 pitches Saturday against the Detroit Tigers despite the discomfort. He allowed 13 hits in 6-2/3 innings but only two runs.
Some with the Tigers told FOXSports.com's Jon Paul Morosi that Harvey's fastball lacked movement Saturday but his velocity was still good and there were no obvious signs of injury.
The 24-year-old Harvey has been one of the few bright spots for the Mets this season, posting a 9-5 record with a 2.27 ERA and 191 strikeouts in 26 starts.
Harvey began the season with a 7-2 record, good enough to earn the start for the National League in July's All-Star Game at Citi Field.
