Port St. Lucie, FL (SportsNetwork.com) - The New York Mets sent starting pitcher Jon Niese back to New York Wednesday in order to have an MRI performed on his sore left shoulder.
Mets manager Terry Collins told reporters that Niese has been experiencing discomfort in his left triceps since the start of the team's spring training camp and had to cut short a recent throwing session.
Niese missed nearly two months of last season due to a partially torn rotator cuff, but did not require surgery. He went 5-2 with a 3.00 earned run average in 10 starts after returning to the mound in mid-August.
In 24 overall starts in 2013, Niese compiled an 8-8 record with a 3.71 ERA.
The 27-year-old, who is tentatively slated to be the Mets' Opening Day starter, won a career-high 13 games while posting a 3.40 ERA the previous season.
