ATLANTA -- By most measures, it had been a good week for the Mets.
With Matt Harvey and Zack Wheeler on the mound, the Mets swept a doubleheader on Tuesday against the Braves, then capped a series victory Thursday night with a 4-3 win.
But some of those good vibes were wiped out when lefthander Jonathan Niese left the game in the fourth inning with what the team is calling left shoulder discomfort.
"It just felt really weak," said Niese, who has battled shoulder woes this season. "The tendinitis kind of flared up again."
Although Niese played down the injury, Terry Collins said the team won't know more until doctors examine the pitcher Friday in New York. "When it bothers you on a night where it's nice and warm . . . I'm a little concerned," said Collins, who pulled Niese almost immediately after he showed signs of pain.
The injury spoiled an otherwise encouraging effort from the Mets, who rallied from a 3-1 deficit to capture this five-game series (3-2) against the division-leading Braves. It was the Mets' first series win since sweeping the Yankees in last month's Subway Series.
David Wright blasted a pair of solo shots off Mike Minor before the Mets used a couple of clutch pinch hits to pull ahead. Andrew Brown homered to tie it in the fifth before Josh Satin's RBI double gave the Mets the lead.
In the eighth, lefty Josh Edgin got Jason Heyward to ground out with the tying run on third base. In the ninth, Bobby Parnell nailed down his 11th save thanks in part to a defensive gem by second baseman Daniel Murphy to rob a sure leadoff hit from Freddie Freeman.
Parnell capped a night in which the bullpen combined for 5 2/3 innings in relief of Niese, who departed after throwing a changeup to Tyler Pastornicky in the fourth.
Niese had allowed three runs on eight hits when he grimaced following his 61st pitch. The lefthander immediately signaled to the dugout for the trainers.
After a brief meeting with Collins, pitching coach Dan Warthen and the team's trainers, Niese departed without attempting a warm-up pitch. Said Niese: "It wasn't worth it."
