NEW YORK - Jacob deGrom struck out 12 batters and carried a perfect game into the sixth inning of his second start all season, pitching the New York Mets past the Atlanta Braves 5-2 on Sunday for their 12th victory in 14 games.
Pete Alonso drove in two runs, and the first-place Mets finished with 19 strikeouts - including three straight from closer Edwin Díaz to end a combined two-hitter. New York took four of five from the Braves in their National League East showdown series, extending its division lead to 6 1/2 games over the reigning World Series champions.
The Braves are also the four-time reigning champions in the division, but the Mets took a big step toward knocking them from that perch - and deGrom put the finishing touch on a series victory that was already clinched with Saturday's doubleheader sweep.
"It was kind of emotional walking out there. I haven't taken this mound in over a year," deGrom said. "I had to take a second and kind of get myself together."
Pitching at home for the first time in 13 months, a dominant deGrom (1-0) retired his first 17 batters - 12 on strikeouts - before walking No. 9 hitter Ehire Adrianza with two outs in the sixth. That ended the longest perfect-game bid of deGrom's career.
Dansby Swanson followed with a two-run homer on the 76th and final pitch from deGrom, making it 5-2.
"He was really good," Braves manager Brian Snitker said. "I'm like, good God, there's nothing wrong with him."
The two-time Cy Young Award winner missed the final three months last season with right forearm tightness and a sprained elbow, then was shut down late in spring training because of a stress reaction in his right scapula. He finally returned Tuesday in a road game against the Washington Nationals, throwing five innings of one-run ball in a Mets loss - a rare occurrence lately.
"It's a really cool thing that we have going," deGrom said. "The goal is to keep it going."

Once play began, however, deGrom didn't disappoint the Citi Field crowd of 37,717.
A standing ovation greeted the 34-year-old ace before he stepped onto the mound, and his first pitch was a 99 mph fastball Swanson lofted into right field for an out. The right-hander then struck out Matt Olson on four pitches, each of which was 100 mph or faster.
"That was fun," Mets manager Buck Showalter said. "(DeGrom) was at the top of his game."
Making his 200th MLB start, deGrom finished with the most strikeouts by a Mets pitcher this season. With shadows creeping over the infield during a late-afternoon start, the Braves swung and missed at each of his first 18 sliders.
Atlanta has lost three straight for the first time all year. The previous team to go that long into a season without a three-game skid was the 2001 Seattle Mariners, who set the MLB record by not losing three in a row until a four-game slide from games Nos. 147-150, according to the Elias Sports Bureau.
While deGrom was silencing the Atlanta bats, the Mets scored four times against rookie Spencer Strider (6-4) in the third.
Brandon Nimmo led off with an infield single and moved to third on Francisco Lindor's single to center. Alonso delivered a two-run double off the third-base bag. Daniel Vogelbach walked and both burly sluggers chugged home on Mark Canha's double to left-center.
Strider needed 79 pitches to complete 2 2/3 innings in the shortest start of his career.
"A lot of weird hits," Strider said. "They seem to be having a lot of luck right now offensively. That's great. It's August. (We'll) see what things are like in October."
New York added another run in the fifth when Jeff McNeil scampered home on a wild pitch.
Joely Rodríguez struck out a career-high four in a season-high 2 1/3 innings in relief of deGrom. Díaz fanned all three batters in the ninth for his 26th save thi syear, finishing the two-hitter.
For the second straight game, Mets fans taunted the Braves in the ninth inning by performing the tomahawk chop.
"It's easy to have fun when we're playing because it's an incredible environment," Alonso said.
Atlanta right fielder Ronald Acuña Jr. was a late scratch from the lineup with lower-body soreness. He flied out as a pinch-hitter in the seventh and remained in the game for the final two innings.
Braves catcher Travis d'Arnaud (right lower leg) was in a walking boot after Alonso slid into him hard on a play at the plate Saturday. X-rays were negative and d'Arnaud is expected to return to the lineup later this week.
