ATLANTA — A lot has happened in the life of Jacob deGrom since he last stepped on a major-league pitching mound on April 8.

A lat muscle strain. The birth of his first child, a son named Jaxon. A hospital health scare with Jaxon that thankfully had a happy ending with the infant home and doing just fine.

One thing has remained the same: DeGrom is still effective as ever. The righthander allowed one run in 5 2⁄3 innings on Sunday in his return as the Mets beat the Braves, 3-2, to sweep the weekend series and complete a 7-2 road trip.

DeGrom (2-0, 1.54 ERA) nearly duplicated his outing from the Mets’ home opener against the Phillies, when he gave up one run in six innings. On Sunday, he needed one more out to get there, but manager Terry Collins decided to take out deGrom after a two-out single in the sixth.

DeGrom threw 82 pitches. He allowed eight hits — all singles — and did not walk a batter. He struck out three.

The Mets won their seventh in a row at Turner Field, which used to be a house of horrors for them. Of course, the Braves used to be a good team, and now they are 4-14 overall and 1-10 at home in their final season at The Ted.

While Mets fans were excited to see deGrom’s return, Braves fans at least got to see top prospect Aaron Blair make his major-league debut. Blair was impressive against a Mets lineup that was without the injured Yoenis Cespedes and the resting David Wright and Travis d’Arnaud.

Blair was charged with three runs in 5 1⁄3 innings. The Mets took a 1-0 lead three batters into the game on singles by Curtis Granderson and Asdrubal Cabrera and a sacrifice fly to left by Michael Conforto.

The Braves tied the game in the fifth on Nick Markakis’ two-out RBI single. Daniel Castro followed with his third hit, a single off deGrom’s glove, to bring Freddie Freeman to the plate. But deGrom got Freeman on a first-pitch comebacker to end the inning.

The Mets scored a pair in the sixth to retake the lead. Granderson walked with one out and moved to third on a single to right by Cabrera. Conforto followed with a ground-rule double that one-hopped over the rightfield fence to make it 2-1 and end Blair’s afternoon.

Lucas Duda then hit a sacrifice fly to center off Alexi Ogando to give deGrom a two-run cushion.

Francoeur served a two-out RBI single to right off Jeurys Familia in the ninth to make it 3-2. After an infield hit by Markakis put the tying run on second, Familia got Castro to ground to second for his fifth save.
