MILWAUKEE — Brandon Nimmo debuted with the Mets in 2016, one year after the team’s unexpected run to the World Series that ended with a Game 5 loss to the Royals.

As the longest-tenured Mets player Nimmo understands this sobering fact better than his teammates: It’s been nine years since the team has won a postseason series.

There was a wild-card berth in Nimmo’s rookie season that ended with a one-game loss to the Giants. And then, in 2022, the Mets lost a best-of-three wild-card series to the Padres at Citi Field.

The Mets began another wild-card series on Tuesday with an 8-4 victory over the Brewers at American Family Field, and for Nimmo just getting here isn’t enough.

“I have been fortunate enough to be a part of three [postseasons], but the biggest thing I have noticed is the teams that make it a regular thing of getting in here, they seem to have the success,” Nimmo said.

The Astros, Braves and Dodgers all fall into that category. Only providing inspiration for the Mets might be the fact that the last two NL pennant winners — the Phillies and Diamondbacks — emerged as wild-card entrants.

The Mets won 89 games in the regular season, and in a sense Tuesday might have felt like an extension of that: They returned to a venue in which they just played three games over the weekend. Also, by playing a doubleheader Monday in Atlanta, the customary workout day before a postseason series was eliminated.

“It actually brings a sense of normalcy to it,” Nimmo said. “Maybe that will work to our advantage.”

Max Kranick was selected to the wild-card series roster to give the Mets a rested arm in the bullpen. Tylor Megill, who started the clincher Monday in Atlanta, was excluded from the roster but can return for the next round if the Mets advance.

Kranick, 27, spent the season at Triple-A Syracuse after returning from a hamstring injury that sidelined him in spring training.

Eddy Alvarez was designated for assignment to create space on the 40-man roster for Kranick. Alvarez, an infielder, is ineligible for the postseason because he arrived in a September trade.

Kodai Senga faced batters in live batting practice Sunday, but it’s unclear what the next step might be for the right-hander, according to manager Carlos Mendoza. Senga reported triceps soreness during a minor league rehab start 1 ½ weeks ago but hasn’t been ruled out as an option for some point in the postseason.

Jeff McNeil is exercising as he awaits the birth of a child after receiving an X-ray on his wrist in recent days. The Mets would have to advance deep into October for McNeil to have an opportunity to return, according to Mendoza.

Brett Baty, Pablo Reyes and Hayden Senger are with the Mets as part of the taxi squad.
