ATLANTA — For a couple of spare parts receiving chances because of the team’s trade-deadline purge, DJ Stewart and Rafael Ortega have fit in nicely with the Mets. 

Stewart’s bat and Ortega’s steady all-around play have been key components during a surge that has at least kept the Mets watchable.

Monday night the outfielders were two of the big contributors in the team’s 10-4 victory over the Braves at Truist Park. 

Stewart homered for the fifth time in six games and brought in another run with a sacrifice bunt and Ortega delivered a two-run homer on a night every member of the Mets starting lineup except Jonathan Arauz reached base. 

The Mets (59-67) won for the seventh time in nine games and have two straight wins against the Braves.

This after Atlanta embarrassed the Mets by outscoring them 34-3 in winning the first three games of their recent series at Citi Field. 

“Everyone knows what happened at the deadline and there was a little bit of a learning period, learning everyone and what they can do, whether you played with them in spring training or not,” said Stewart, a former first-round draft pick by the Orioles who spent most of the season at Triple-A Syracuse. “We’re just getting comfortable with everyone and I think you’re kind of seeing that on the field and the clubhouse is upbeat and we’re enjoying playing with each other.” 

David Peterson lasted 4 ²/₃ innings for the Mets — his longest outing in four starts since returning to the rotation — and allowed four earned runs on seven hits with four strikeouts and two walks.

It was a third straight shaky start for the left-hander, who walked six batters in only 3 ²/₃ innings last week against the Pirates. 

Phil Bickford, Sam Coonrod, Adam Ottavino and Drew Smith combined to pitch 4 ¹/₃ scoreless innings in relief. 

“I definitely wanted to go deeper into the game,” said Peterson, who was without a pitch-count restriction for the first time since his rotation return. “[The Braves] made it tough. They are a good team and I felt like, even though I gave up some runs, we kind of jumped back on them.” 

Stewart homered in the second inning for the game’s first run and Ortega’s two-run blast later in the inning extended the Mets’ lead to 3-0.

Stewart’s homer was his sixth of the season and Ortega’s was his first. The Mets have homered in eight straight games and hit 20 during that stretch (including Francisco Lindor’s three-run blast in the sixth inning). 

Ortega, a 32-year-old journeyman, has been more noticeable with his glove and base-running than his bat. His homer was his first since arriving from Syracuse on Aug. 1. 

“There’s a reason Ortega keeps getting chances,” manager Buck Showalter said. “You are looking for trustworthy players.” 

Marcell’s Ozuna’s homer in the bottom of the second recovered a run for the Braves before Michael Harris II stroked a two-run double in the third against Peterson that tied it 3-3.

Orlando Arcia and Ronald Acuna Jr. both singled ahead of Harris to begin the rally. 

Ozuna’s second homer of the game, a blast leading off the fourth, put the Mets in a 4-3 hole.

The Braves threatened later in the inning, when Vaughn Grisham singled following a walk to Arcia, but Peterson struck out Acuna to end the threat. 

The Mets scratched for a 7-4 lead in the fifth on four straight singles following a walk to Brandon Nimmo.

Jeff McNeil, Pete Alonso and Daniel Vogelbach each brought in a run with a single before Stewart’s safety squeeze allowed Alonso to score from third.

All seven runs were charged to Braves starter Allan Winans, who allowed nine hits and one walk over 4 ¹/₃ innings. 

Lindor’s three-run homer in the sixth buried the Braves in a 10-4 hole.

Ortega walked and Nimmo singled before Lindor cleared the fence in left-center for his 23rd homer of the season.
