Mets To Continue Walking in a Winker Wonderland

When the Mets signed Juan Soto in December, he was, technically speaking, filling the hole that Jesse Winker left behind. Of course, that’s a bit like buying the Batmobile to replace an expired bus pass. Winker’s greatest strength is drawing walks, and Soto’s career walk rate makes Winker’s career walk rate look like Jeff McNeil’s career walk rate. Still, the point stands. The Mets lost one lefty-batting corner outfielder to free agency and replaced him with another. Yet, on Thursday afternoon, they re-signed Winker anyway. His one-year, $7.5 million contract is fairly straightforward, but the ramifications for New York’s roster could be much more complex.

Poor baserunning, miserable defense, and frequent injuries have limited Winker throughout his career. All the same, his bat was a major asset for the Reds from 2017-21. In just over 1,500 plate appearances with Cincinnati, he slashed .288/.385/.504 with a 132 wRC+. While he thrived at Great American Ball Park, he made his mark outside of that hitter’s haven, too, producing an .845 OPS and 126 wRC+ on the road. He made the All-Star team in his final season with the Reds, batting .305 with 24 home runs in 110 games, good for a career-best 3.2 WAR.

The next two seasons, however, marked a period of steep decline for Winker. Playing for the Mariners and Brewers, he managed just 0.7 WAR in 2022 and -0.8 in 2023. His agent might point out that back, neck, and knee injuries hampered his performance in that time, as did some bad luck on balls in play; his xwOBA was nearly 30 points better than his wOBA, while his BABIP was more than 50 ticks below his average from the previous five years. Even so, it would have been more than fair to worry about his future as a major leaguer after his dismal 2023 campaign. Entering 2024, his ZiPS projection was a mere 0.4 WAR in 415 plate appearances, and he was forced to sign a minor league contract with the Nationals less than two weeks before spring training began.

Back to full health, Winker rebounded in Washington. While he wasn’t a power threat like he’d been in his Reds heyday, he knocked 18 doubles and 11 home runs, giving him a middle-of-the-pack .162 ISO. His BABIP was back up above .300, and his 14.0% walk rate ranked fifth among qualified batters (as of his final day with the Nats). All in all, he put up a 125 wRC+ and 1.2 WAR in 101 games.

This was enough to pique the Mets’ interest ahead of the trade deadline. However, after Washington sent him to New York, Winker wasn’t the productive hitter that the Mets thought they were getting when they acquired him. Well, at least not during the regular season, when Winker was little more than replacement level with his new team. All the more disappointing, he was set up to thrive with the Mets: He had the platoon advantage almost every time he came to the plate. While Washington used him as an everyday player, New York shielded him from southpaws; he faced just four left-handed pitchers over the final two months of the season. Nonetheless, his 97 wRC+ with the Mets was much closer to his career mark against lefties (88) than righties (129).

The problem was rooted in Winker’s approach at the plate. With the Nationals, he ran that aforementioned 14.0% walk rate and struck out just 22.2% of the time. After the trade, he lowered his strikeout rate to 17.1%, which might’ve been a good thing, except that his walk rate also dropped way down, to 7.8%. With the Mets, Winker swung more often and made more contact, especially on pitches in the strike zone. His Z-Swing% (per Statcast) jumped from 60.5% to 70.4%, while his Z-Contact% jumped from 85.5% to 91.2%. This wouldn’t have been a problem if he crushed many of those extra balls he put in play, but, naturally, he did not.

So, why did Winker suddenly change his approach at a time when things were going well? I’d posit the Mets noticed that he was holding back on too many hittable pitches over the first four months of the season and let him know that was the case after the trade. According to Robert Orr’s calculations from his Damage leaderboard, Winker was better than the average hitter at identifying hittable pitches every year from 2020-23. Yet, with the Nationals this past season, his Hittable Pitch Take rate put him in the bottom third of the league. After he started swinging at more strikes with the Mets, he rose back up to the 66th percentile. The problem, however, was that he sacrificed another critical skill in the process. Winker’s selectivity rate — Orr’s metric that shows how often a player avoids swinging at bad pitches — fell from the 73rd percentile as a National to the 35th percentile as a Met. All that is to say, Winker swung at more good pitches, but he also swung at more bad ones, and he didn’t do enough damage against good pitches to compensate for his lack of production against the bad ones. Ultimately, his hard-hit and barrel rates were lower with the Mets than they were with the Nationals, as were his wOBA and xwOBA on contact.

This raises another question: Why would the Mets want Winker back if their efforts to improve his approach went so poorly? Perhaps they think he just needs a little more time to reap the rewards. After all, 129 plate appearances is nothing. Aaron Judge was still hitting below the Mendoza Line with an OPS in the mid-.700s by his 129th plate appearances last season. Thankfully for our purposes, we have an easy way to increase the sample size of Winker’s 2024 season with the Mets: Include the playoffs, as Winker took an additional 32 plate appearances in October. He continued to swing at strikes at a similar rate, but he used those swings to record several big hits, including two triples and a home run. He also drew seven walks, compared to just four strikeouts. If you combine those numbers with Winker’s regular season stats as a Met, you get a 10.6% walk rate, a 16.1% strikeout rate, and a .341 wOBA. Even more promising is his .353 xwOBA, notably higher than his .335 xwOBA with the Nationals. All of a sudden, it makes a lot more sense why the Mets decided to keep this guy around.

It’s far too soon to say if Winker’s new approach will work in a larger sample size. Still, it’s not hard to see why the Mets think he’s worth a longer look. In a best-case scenario, he could be an even more productive hitter than he was overall in 2024. And if this new approach doesn’t befit him going forward, he doesn’t have to be anything more than the hitter he was in Washington to be valuable on a one-year, $7.5 million deal. After all, the Mets will continue to shield him from left-handed pitching, and his track record against righties is strong:

So, that’s Winker. But this signing is an iceberg – and ironically, it’s the rare kind of iceberg that isn’t so good for a polar bear. At first glance, this is just a 1.0- to 1.5-WAR player signing a short-term deal commensurate with his talents. Yet, there’s a lot more to it than what you see on the surface. When SNY’s Andy Martino first reported the Winker signing, he added that the Mets are now preparing for life after Pete Alonso. Indeed, while no one could argue that Winker is a direct replacement for the All-Star first baseman, there is a connection between this signing and the Mets’ possibly giving up on Alonso if you follow the trail of dominoes far enough.

With Soto, Brandon Nimmo, Jose Siri, and Tyrone Taylor to man the outfield, the Mets are likely to use Winker as their primary DH against right-handed pitching. However, he can still play the corner outfield if he needs to; he spent 95 games on the grass last season, including 27 with New York. So, in the event of an injury to one of the team’s other outfielders, Winker can fill in. That means the Mets are less likely to ask McNeil to play the outfield in 2025. Instead, he can ideally play second base almost every day. As long as McNeil is covering the keystone, the Mets won’t need any of their young infielders at second base, therefore allowing Brett Baty, Luisangel Acuña, and Ronny Mauricio to focus their efforts on third. If just one of them, or some combination of the three, can competently cover the hot corner, Mark Vientos will be able to play first base full-time. Long story short, Winker improves the outfield depth, which indirectly improves the infield depth, which should allow Vientos to formally replace Alonso at first.

Another aspect to the iceberg is how this all affects Starling Marte, whose Gold Glove years are long behind him. In 170 games in the outfield over the past two years, he has accumulated -13 DRS, -14 OAA, and a -12 FRV. Meanwhile, neither ZiPS nor Steamer sees him as much more than a league-average bat. As a righty hitter, he could theoretically platoon with Winker at DH. After all, he posted an impressive 141 wRC+ against left-handed pitching last year. Yet, even with the platoon advantage, Marte might not be a strong enough hitter to warrant the reps. While he has had positive platoon splits the last three years, he had reverse platoon splits every year from 2014-21. In other words, he’s hardly a guaranteed lefty masher. On the contrary, ZiPS projects him for a .698 OPS against lefties and a .713 OPS against righties in 2025. Even if the Mets were willing to give a roster spot to the short side of a DH platoon, Marte probably wouldn’t be that guy.

The final component of the iceberg is what the Mets do next. Steve Cohen’s pockets are already deep, but if the Mets aren’t going to give Alonso a multi-year contract, and if they can get someone to take on any of Marte’s remaining salary, they’ll only have more to spend. With a projected payroll still $49 million below last year’s final tally and a luxury tax payroll still $17 million below the top penalty threshold, the Mets remain major players to watch as the offseason rolls on.
