If David Wright was breaking a sweat, it wasn’t over his slow start. The Mets captain, who has battled flu-like symptoms in recent days, realizes it’s much too early to be concerned with his anemic numbers. But it certainly was a positive sign for the Mets that Wright went 2-for-4 in the team’s 4-3 loss to the Braves on Wednesday night. Wright snapped an 0-for-13 skid with a single against Ervin Santana in the fourth and also singled as part of the Mets’ three-run rally in the ninth. Wright, who raised his average to .233, took extra batting practice during pregame, but refused to blame his struggles on whatever bug is going around the Mets clubhouse. “I am getting some pitches that I should be doing more with than I am,” Wright said. “I’ve gotten in some good situations where I’m just missing pitches or hitting a ball hard, but right at people. Hopefully those start falling in. Once you get a couple of those to fall in, it seems like you can get on a roll a little bit.” Manager Terry Collins expects a breakout from Wright. “This might be the best day he’s felt health-wise in about four,” Collins said. “In the years that I’ve been here, you look up at this time of year and this guy is hitting .400, so this is a little bit of a difference for him.
