Mets Rumors

The Marlins were the sport’s most active seller on deadline day, showing willingness to listen on virtually every short-term asset they had while also targeting controllable young players around whom they could potentially build future iterations of the club. One player sought by Miami’s front office was within their own division; the Fish showed “heavy interest” in third base prospect Brett Baty, reports Mike Puma of the New York Post, adding that Miami was one of multiple clubs interested in buying low on the former first-rounder and top-100 prospect.

Selected 12th overall back in 2019, Baty ranked on MLB.com’s top-100 prospects list every year from 2020-23. By the time the 2022-23 seasons rolled around, just about every publication of note ranked Baty among the game’s 50 or so best prospects. He and current third baseman Mark Vientos — second-round pick in 2017 — ranked highly in the Mets’ system throughout their prospect tenures, but it’s Vientos who’s taken the reins at third base and run with the opportunity. In 259 plate appearances this season, the 24-year-old Vientos owns a hearty .280/.336/.547 slash (148 wRC+) with 16 homers and 15 doubles.

The emergence of Vientos naturally led to some speculation regarding Baty in the lead-in to last month’s trade deadline. However, Vientos’ presence alone hardly means there’s no long-term fit on the roster for Baty. He’s seen minor league work at second base and also played left field in the majors. Current second baseman Jeff McNeil is no stranger to the outfield corners and could shift there. The Mets will also see both Pete Alonso and J.D. Martinez become free agents at season’s end. Baty is considered a superior defender at third to Vientos, so if Alonso and/or Martinez depart in free agency, Vientos could work in more of a first base/DH role next year (or rotate between the two infield corners and DH). That’d free up third base for Baty — if he hits enough to merit the opportunity.

To this point in his career, Baty simply hasn’t done that. He’s played in parts of three big league seasons but managed only a .215/.282/.325 batting line (73 wRC+) in 602 trips to the plate. However, he was also rushed to the majors in ’22 despite only having six games of Triple-A experience to his credit. And, of course, Baty would hardly be the first prospect to struggle at the plate in his first few MLB looks before hitting his stride in his mid-20s. Even Vientos flailed away at a .205/.255/.354 clip through his first 81 games in 2022-23 before hitting his stride in the majors this year.

It’s worth noting that while he didn’t hit in the majors this season, Baty’s still showing plenty of promise in Syracuse. He’s taken 203 turns at the plate with the Mets’ Triple-A club there and posted a sound .260/.360/.497 line (119 wRC+) with 11 homers, eight doubles, a big 12.8% walk rate and a lower-than-average 18.7% strikeout rate. Baty still has a minor league option remaining beyond the current season as well, so even if he struggles next spring or early in the season, he could still be freely sent to Triple-A for additional refinement.

Ronny Mauricio has missed the entire season due to a torn ACL but will be back in the mix next year. A top prospect himself, he has hit at least 20 home runs in each of the past three minor league seasons while playing shortstop, second base and third base. He recently underwent surgery to clean up some scar tissue in his right knee, per Will Sammon of The Athletic on X, but that isn’t expected to have a noticeable impact on his timeline. Francisco Lindor has shortstop locked up for the foreseeable future but Mauricio could eventually factor into the infield picture at third or second base, depending on other developments around the roster.

The offseason will be interesting with regard to the Mets’ corner mix. They’ll surely receive interest in Baty again while simultaneously exploring the possibility of keeping a franchise cornerstone (Alonso) and a still very productive veteran DH (Martinez). Baty could arguably be used as a trade chip to acquire help on the pitching front — Luis Severino, Sean Manaea and Jose Quintana can all become free agents at season’s end — but there’s also a possible long-term role to be had in Queens, especially if Alonso signs elsewhere.

From the Marlins’ vantage point, targeting Baty is perfectly sensible. They don’t have a long-term solution at third base. Jake Burger has handled that spot regularly since being acquired prior to the 2023 deadline, but he’s a defensive liability whose free-swinging, low-OBP approach at the plate leads to wild fluctuations in terms of offensive output. He’s better suited at first base or at designated hitter. Deadline pickup Graham Pauley could get a long-term look at third, but he’s a versatile prospect who could bounce around the diamond in a semi-regular role.

Adding Baty and his remaining five seasons of club control surely holds some appeal, but the Mets are presumably wary of sending Baty to another NL East club and watching him blossom into a regular. Still, the Marlins will have pitching to peddle again this winter (e.g. Jesus Luzardo, Braxton Garrett, Ryan Weathers and potentially even former Cy Young winner Sandy Alcantara), so they could rekindle their interest in Baty. He’ll likely draw interest from both rebuilding teams and others simply looking for a long-term option at the hot corner, but it’s far from a given that the Mets will actually move Baty this offseason.
