Travis d’Arnaud shouldn’t get too comfortable batting eighth.

If this pace continues, he is going to be find himself hitting in the middle of the order soon.

“We’re hoping to move him up. We want to get him some more at-bats [in the eighth spot in the lineup],” Mets manager Terry Collins said before d’Arnaud went 2-for-3 with the go-ahead, two-run single, which proved to be the game-winner, in the fourth inning of the Mets’ 4-3 victory over the Cubs at Citi Field on Saturday night — the Amazin’s third win in a row after losing four straight. “He’s swinging better, that’s the main thing.”

Since returning from the disabled list on June 21, d’Arnaud is 10-for-32 with five RBIs, giving the Mets the kind of offensive production behind the plate they sorely lacked in the after missing 50 games he missed with a right shoulder rotator cuff strain. Collins credited it to d’Arnaud’s long rehab assignment — he got 41 at-bats in the minor leagues.

“When he got up here, he had his swing,” the manager said.

D’Arnaud, now hitting .244, continued his production at the plate Saturday night. He had two hits — his second multi-hit game in the past three contests and third in his past five starts — including the tie-breaking single in the fourth, when he got just enough of a 94 mph Jake Arrieta fastball to plate two runs with a blooper to center field. He also rifled a single in the sixth, perfectly executing a hit-and-run with Alejandro De Aza.

“We were just looking for a pitch to handle and try to put a good swing on it,” he said, referring to the two-run single. “Fortunately, I was able to find a hole and two runs were able to score.”

D’Arnaud has hit low in the batting sore since returning, either seventh or eighth. But he has been productive down there, driving in the two runs on Saturday and starting a three-run rally Thursday night with a single. But, as Collins hinted, his spot there may not last long if his current pace continues.

D’Arnaud still is waiting for his extra-base power to come back. He only has produced singles since returning, and has just three doubles and no home runs on the season, a span of 78 at-bats, after hitting 12 home runs, 14 doubles and 41 RBIs in 239 at-bats last season.

“Things like that I don’t focus on,” he said. “I focus more on how we play in the field and if we win or not.”

Perhaps those extra-base hits will come when he gets moved up in the batting order.
