The Mets have remained at the top recently by relying on the bottom (of the lineup).

While much of the lineup has struggled, their Nos. 7-8-9 hitters have come through in the past week.

James McCann is finally showing signs of the bat that made the Mets lock up the catcher on a four-year deal. Eduardo Escobar is riding a six-game hitting streak and playing his best baseball of the season. Tyler Naquin and Mark Canha — when he’s down in the order — have swung better and helped lengthen the lineup.

During Wednesday’s doubleheader sweep in Pittsburgh, the Mets received a total of 12 hits from the bottom three spots in their lineup. From the start of September through the end of the doubleheader, the Mets’ .971 OPS from their seventh, eighth and ninth hitters was second-best in baseball, behind only the Rays’ bottom three.

“If, one through nine, anyone can hurt you, it makes it extremely tough to navigate a lineup,” McCann said after going 1-for-3 with two walks Wednesday. “Especially when 7, 8, 9 is getting on base like we were. A lot of RBI guys have multiple chances to drive guys in — that makes it extremely tough.”

Among the lower-down hitters, McCann’s emergence could prove the largest. With the White Sox, McCann was a 2019 All-Star and 2020 slugger (seven home runs in 31 games), which he used to land a long-term pact with the Mets.

He did not hit last season, and the 32-year-old’s 2022 has been a mess. Surgery to address a broken hamate bone in his left wrist cost him nearly seven weeks in May and June, before an oblique strain cost him almost four weeks in July and early August.

In between those injured list stints, there was little offensive production. McCann said the biggest difference in his swing right now is health.

“Everything I’ve been working on is finally getting to that point where I want to be,” said the catcher, who is batting .201 with a pair of homers this year but has looked much better since returning from the IL. “Unfortunately how the season has gone for me is I’ve had starts and stops, start, stop. It’s been a grind to get that groove. That’s what I’ve been able to get the past couple weeks.”

The same can be said for Escobar, who had fallen into a platoon role at third base with first Luis Guillorme and then Brett Baty. The 33-year-old has been excellent since returning from an oblique strain in late August and is batting .526 in his past six games with three home runs.

Add in the recent stroke of Naquin, who is 5-for-11 in his past three games, and the bottom of the order has come alive.

“We knew that they’re good hitters. It’s just a matter of them clicking,” Francisco Lindor said Wednesday. “They’re having their moment right now.”

McCann was named the Mets’ nominee for the Roberto Clemente Award, which goes to the player who “best represents the game of Baseball through extraordinary character, community involvement, philanthropy and positive contributions, both on and off the field.”

Each team nominates one player for the league-wide award.

McCann, a first-time nominee, has helped families with children receiving care in the Newborn Intensive Care Unit. In June, McCann visited Cohen Children’s Medical Center in Queens, then donated a suite to a Mets game to nurses he met on the visit.

McCann and his wife, Jessica, have a pair of twins who spent their first seven weeks in the NICU.
