"&lt;p&gt;&lt;/p&gt;&lt;p&gt; Mets starter Jon Niese left Thursday's start with a shoulder injury. (Scott Cunningham/Getty Images)&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;New York Mets starter Jon Niese left Thursday night's start against the Atlanta Braves with apparent shoulder discomfort, according to multiple reports.&lt;/p&gt;&lt;p&gt;Niese's discomfort became apparent when he winced after a fourth-inning pitch to\u00A0Tyler Pastornicky. The Mets' training staff immediately came out to check on Niese, who then left the game.&lt;/p&gt;&lt;p&gt;According to ESPN.com's Adam Rubin, Niese has been battling what the team has labeled left-shoulder tendinitis. In 14 starts so far this season, Niese is 3-6 with a 4.32 ERA. He has 49 strikeouts and has walked 33 batters in 77 innings.&lt;/p&gt;&lt;p&gt;Niese's injury could solve the Mets' rotation surplus problem, however. The Mets were planning on temporarily shifting to a six-man rotation with top prospect\u00A0Zack Wheeler\u00A0debuting this week.&lt;/p&gt;&lt;p&gt;Jon Niese winced on the last pitch and pointed to the dugout. He's leaving game. #mets&lt;/p&gt;&lt;p&gt;\u2014 Adam Rubin (@AdamRubinESPN) June 21, 2013&lt;/p&gt;&lt;p&gt;Jon Niese has been bothered recently by what the team labeled shoulder tendinits.\n\u2014 Adam Rubin (@AdamRubinESPN) June 21, 2013&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
