Are Mets' big moves wrapped up ... or is there room for more?

NEW YORK -- There is no universe in which Mets president of baseball operations David Stearns would ever say his team is done adding players. Stearns loves to tinker; he adds during Spring Training and throughout the season. As such, the group of Mets that arrives at Spring Training next month won’t be nearly the same as the one that ends the season.

A better question is this: After adding Bo Bichette, Luis Robert Jr. and Freddy Peralta in rapid succession last week, are the Mets done making significant moves?

“We’re always open to improving the team,” Stearns said last week. “I think we’ve checked off some of the main goals of the offseason, but if there are opportunities to get better, we’re going to explore them.”

Translation: Perhaps another notable move is coming, but don’t count on it.

The buzziest name remaining on the market is left-hander Framber Valdez, who has been linked to the Mets at various points this winter. Right now, New York’s rotation is lined up to include some combination of Peralta, Nolan McLean, Clay Holmes, Sean Manaea, David Peterson and Kodai Senga, with Tobias Myers, Jonah Tong, Christian Scott and Justin Hagenman among those fighting for jobs behind them.

The Mets don’t necessarily need another starting pitcher, but it could never hurt to add one of Valdez’s caliber -- a two-time All-Star who has twice cracked the Top 20 of American League MVP voting. It’s worth noting that Stearns has been reluctant to give out long-term contracts to anyone, and it’s highly unlikely he’ll change that policy for a 32-year-old pitcher from outside the organization. But the fact that Valdez is still available suggests he could possibly be had on a short-term deal. If that winds up being the case, perhaps the Mets could pounce.

Other remaining free agent starters include Zac Gallen, Chris Bassitt and Lucas Giolito.

Elsewhere on the roster, an obvious area of uncertainty is left field, where No. 2 prospect Carson Benge is set to compete against Tyrone Taylor and Brett Baty for playing time. Benge has just 24 games of experience above Double-A, while Baty is attempting to learn a new position on the fly and Taylor is coming off a season that saw him post a .598 OPS. For those reasons, it would make sense for the Mets to add some veteran stability.

The problem is that precious few such options exist. Now that Harrison Bader has signed in San Francisco, the most sensible left-field addition would probably be Austin Hays, a veteran who hit .319/.400/.549 against left-handed pitching last year. But a source said the Mets have not expressed any recent interest in Hays, which makes sense given Stearns’ public comments. The president of baseball operations has been adamant about wanting to give opportunities to younger players, and the addition of someone like Hays would potentially cut into the playing time of Benge. In other words, don’t expect a major transaction in this area.

Finally, the relief corps is always a place the Mets can upgrade. Right now, the Mets have four bullpen locks in Devin Williams, Luke Weaver, Brooks Raley and Luis García. A fifth veteran, A.J. Minter, may not be healthy enough to join the team on Opening Day but should do so early in April. A sixth, Huascar Brazobán, is out of Minor League options and stands a strong chance of making the team for that reason.

That still leaves two spots up for grabs, which -- similar to the outfield -- is just the way the Mets like it. A slew of younger relievers, headlined by right-hander Dylan Ross, is set to compete for jobs. Myers may play a role, and recently signed veteran Craig Kimbrel could, too. But remember: Two years ago, the Mets entered the season with a “frozen” bullpen, stocked with pitchers on guaranteed contracts or those out of options. In a perfect world, the team would give itself a bit more flexibility.

As for the roster as a whole, Stearns summed the situation thusly: “We’ve still got time before Spring Training. I imagine there are going to be transactions in Spring Training as well. There always are. So we’ll keep busy. We’ll keep in touch with both the trade market and the free agent market. In terms of what exactly is next, I don’t know. But we’ll keep working at it.”
