PHILADELPHIA — Summer arrived Sunday, five minutes past 8 p.m., when Kyle Schwarber unleashed another mighty swing. He stood and admired it for a second. The view is decent from here; it was not a sellout at Citizens Bank Park, but it felt like it was supposed to feel like during another win, 6-2 over the floundering New York Mets. The Phillies are closer to first place than they’ve been in more than two months.It is fun again.“I mean, just get us in,” Bryce Harper said. “That’s our biggest thing. That’s our motto. Every year, we want to get in. Obviously, we want to win the division. That’s our main goal right now, to fight and claw back and win the division. But we just want to get into the postseason and see what happens.”The Phillies (42-35) are tied for the sixth-best record in the majors, a fact that sounds fabricated. They are flawed. They are maddening. And they have won five of their last six series. They are 6 1/2 games back of the Atlanta Braves, the smallest deficit since April 19.They are different when Schwarber and Harper, two 33-year-old stars, are doing spectacular things. It is not guaranteed — none of it. The Phillies were 9-19 at one point. Everyone is a year older. It makes them want to hold onto moments like this weekend.Zack Wheeler thought about it during Saturday night’s game. He wasn’t pitching. He was watching.“You hear about all the greats before you, so to speak,” Wheeler said. “You watch them as a fan. I’m actually here watching these guys do some magic and do something special career-wise. It’s been going on a long time now. They’re putting together unbelievable careers, and it’s fun to be present and watch that happen live.”
