Ryan Madson gave up six of the runs in Wednesday’s big rally, and Michael Conforto said the Mets had clearly benefited from seeing him so much. But there also could be something to the makeup of their lineup.

On Wednesday, the Mets’ second through seventh hitters were all over 30 years old. Players decline in their 30s, as we know, which is why older players found such lukewarm interest in free agency last winter. But perhaps if those players are good enough — and well rested — their experience can make a difference.

“Everybody talks about age, but I feel like I’m one of the hardest workers out there at age 32, and some of these other guys too on this team,” said third baseman Todd Frazier, who signed with the Mets in February for two years and $17 million, after earning more than $20 million the last two years.

“It was a tough off-season, it was terrible, people don’t really know what we went through. I’m not trying to prove anything, but at the same time, I’m trying to show I can still do it and still put up numbers at this age.”

His numbers are stellar — a .291 average, 13 runs batted in and a team-high 15 walks — like those of second baseman Asdrubal Cabrera, whose $8.25 million option the Mets exercised in November. Cabrera is hitting .343 with four homers, and while his average almost certainly will fall, Cespedes, at .217, will almost certainly improve.

“The reason we believe is we have a lot of different ways to score runs and prevent runs and win games,” right fielder Jay Bruce said.

Well, he was told, the Mets don’t have much speed.

“But we run the bases,” Bruce said. “Look at Asdrubal. You don’t have to be fast to run the bases well. Guys are getting base hits; we’re not all or nothing. We’re taking good at-bats, Todd is walking. You don’t want to be the guy to take the bad at-bat. It’s a concerted effort of not letting the game speed up on us.”
