NEW YORK — On Wednesday, in discussing how his bullpen plans shift moment to moment over a nine-inning game, Carlos Mendoza chuckled at the idea of forming a pregame plan and sticking to it.

“I don’t know that there’s ever a time you come up with a game plan and stick to it,” the Mets manager said. “Every time you make an adjustment because the game unfolds. … You have an idea, but then you have to make adjustments.”

Perhaps Mendoza’s boss, David Stearns, should take that advice when it comes to this season.

The Mets entered 2024 with a clear, consistent plan from ownership down to the clubhouse. While they did not possess the high expectations of previous spring trainings, they thought they could be legitimate contenders for the postseason while preserving a sustained window of contention in the future. And here they are, days ahead of the trade deadline, as legitimate contenders for the postseason who have preserved a sustained window of contention in the future.

But after another memorable win Thursday night, a walk-off 3-2 victory over Atlanta that felt like the inverse of so many nightmarish nights at Turner Field, maybe it’s time for Stearns and the New York front office to get a little greedy about 2024. Yes, the Mets are going to be buyers at the trade deadline. But let’s make a case for the Mets to do more than add a reliever in the next week, a case for the Mets to be aggressive buyers like they last were en route to an unexpected pennant in 2015.

The Mets are good enough

Let’s do some blind resumes for teams on the morning of July 26 over the years.

OK, blindfolds off! What do those pretty similar teams all have in common? They all won the pennant.

They were also pretty aggressive at the trade deadline. I classified the 2018 Dodgers (Manny Machado) and 2022 Phillies (David Robertson, Brandon Marsh and Noah Syndergaard) as All-in Buyers — teams that surrendered significant prospect capital for the present. The 2019 Nationals added three relievers, including the guy who would record the final out of the World Series. In 2021, Atlanta brought in four outfielders, including the NLCS and World Series MVPs. In 2023, Arizona dealt for a closer to better position itself for the postseason.

(For what it’s worth, the 2015 Mets, another All-in Buyer, were 50-48 with a negative-seven run differential on July 26.)

No, the Mets lack the kind of rotation and bullpen you generally rely on to carry you in October. However, New York possesses an offense that appears built for the postseason. As evidenced by its bashing of Gerrit Cole twice in the last month, the Mets’ lineup can go deep with the best of them. Only Baltimore has hit more homers since the Mets’ hot streak started May 30, and they’re tied for fourth in the majors in homers on the season — ahead of everyone but the Dodgers in the National League. On Thursday, New York was in the game against a dominant Chris Sale because Francisco Lindor turned one Sale mistake into two Mets runs.

Homers carry offenses come October. The similarly productive but differently constituted offense in 2022 tied for 15th in the league in home runs, then watched Atlanta and San Diego outhomer it in the biggest games of the season. This Mets offense can swing a short series with its power.

The National League is open

Here’s an important caveat: If I covered the Pirates or the Reds or the Padres or the Diamondbacks, I’d probably be making the exact same case. Because the National League is as open as it’s been in years.

Los Angeles and Atlanta have been the two best teams in the senior circuit for the last several seasons. Both are enduring more turbulent regular seasons than they’re accustomed to. The Dodgers continue to have health questions about their rotation, a dynamic that doomed them last October. Atlanta’s best hitter and best pitcher are out for the season. Its lineup looks like a shell of what the Mets are used to confronting.

While the Phillies have taken the mantle of the NL’s team to beat, they’re a team the Mets are pretty good at beating. They memorably went 14-5 against Philadelphia in 2022, and even during a down 2023 went 6-7 against it. This year, the Mets are 2-4 against the Phillies. And remarkably, since the start of the 2022 season, New York is 10-3 when facing either Aaron Nola or Zack Wheeler.

The timing actually clicks

It’s really tempting for teams to try manipulating their window of contention — to be cautious this year to put more eggs in a basket down the line. In doing so, however, they often miss the year to win.

The 2015 Mets could have been more cautious: Syndergaard and Steven Matz were rookies, Wheeler was hurt, the NL had several very good teams — surely the Mets’ best chance to advance in October would be down the road? As it turns out, that young rotation was never as healthy or as dominant as it was right then and there, and the Mets’ aggressiveness paid off in a pennant.

(Contrast that with the 2013-2015 Pirates, who never made the big move to push a very good team over the top. They still haven’t won a postseason series since 1979.)

For the Mets, it’s also fair to ask: What year, specifically, are they waiting for? Injuries to some key prospects this year mean New York won’t head into spring training 2025 planning to give an everyday spot to a talented rookie. The full incorporation of guys like Jett Williams, Drew Gilbert, Luisangel Acuña and Ryan Clifford won’t happen until 2026 — by which point Lindor will be 32 and Brandon Nimmo 33, on the outskirts of their primes.

The goal is to open a sustained window of contention and pounce on legitimate opportunities to win divisions, pennants and championships. The Mets are there. The two players they have signed long-term are having career-best years. Their cornerstone first baseman might not be here next year.

The window of contention is already open.

What does this mean?

Let’s be honest: This is where most columns like this end. There’s all that reasoning for going for it, now it’s Stearns’ job to turn that into something.

But I’d be remiss if I didn’t mention that the current shape of the deadline market makes it difficult to go for it. Teams like the Pirates and Reds and Padres and Diamondbacks are all still in it in the National League, and the number of sellers is tinier than usual. The best starter likely to be traded may not be able to start much more this season. The best reliever likely to be traded has a walk rate you wouldn’t comfortably hit on in blackjack.

It’s harder to provide the kind of blueprint for the deadline that I do for the offseason because acquisition costs in trades are so much more difficult to project than open-market salaries. So I’ll settle for suggestions that would fit more of an all-in approach.

1. Engage the White Sox on Garrett Crochet with the understanding you’d be acquiring him to pitch out of the bullpen in 2024. The Athletic reported Thursday that Crochet would prefer to stay on a starter’s schedule (albeit with limited innings) down the stretch of this season unless an acquiring team signs him to a contract extension.

As I outlined Thursday morning, the Mets could use a long-term ace. Here’s a 25-year-old left-handed All-Star who leads the league in strikeouts and is interested in a long-term extension. Those all feel like good things. (Like Wheeler, Crochet’s likely arbitration salaries for the next two seasons will be suppressed by his lack of availability up to this point in his career. Thus, a long-term extension would cost less against the luxury tax than it might otherwise.)

Trade for Crochet, extend him and make him a multi-inning reliever with scheduled appearances the rest of the way. Imagine him coming in behind your right-handed starters in the postseason and serving as a one-man bridge to Edwin Díaz. Put him back in the rotation in 2025 and beyond. That might be worth the significant package of prospects it would require, as it would mean the Mets wouldn’t have to dive into the deep end of the starting pitching market this winter for a free agent already in his 30s.

2. If Crochet proves too much, combine a rotation upgrade — chiefly, a pitcher who misses more bats than the current starters — with two additions in the pen and one to the bench.

In the rotation, Detroit’s Jack Flaherty and Toronto’s Yusei Kikuchi come to mind. Flaherty will cost a good amount, but he too could become a viable option to re-sign.

For the bullpen, one high-leverage lefty should be the priority. Scroll past Tanner Scott to his teammate Andrew Nardi or to The Athletic’s years-long target Andrew Chafin of the Tigers. Another multi-inning arm could help keep the group fresh, as well. Cincinnati’s Buck Farmer or Detroit’s Alex Faedo could work there.

The final piece would be a versatile bench contributor who could protect the Mets against regression or injury at a few different positions. Detroit’s Andy Ibañez, Tampa Bay’s Amed Rosario, Toronto’s Isiah Kiner-Falefa and Oakland’s Abraham Toro could fit that role.
