OFNew York Mets
April 26, 2026
Slater and the Mets agreed on a contract Sunday, Chelsea Janes of SNY.tv reports.
Analysis
Slater will head to the Big Apple after being designated for assignment by the Marlins on Wednesday. The outfielder cleared waivers and electing free agency Sunday, and he has now quickly found a new home. Slater struggled to a .174 average with an RBI, a run scored and a stolen base over 23 at-bats with Miami this season, but he owns a .777 career OPS versus left-handed pitchers, and he'll likely get a shot to start against southpaws with New York. Tommy Pham was designated for assignment by the Mets on Sunday, freeing up a spot on both the 40-man roster and major-league squad for Slater.

2020
2019
2018
Slater signed a one-year deal with the White Sox this offseason and is projected to be a right-handed option off their bench to perhaps platoon at DH or with newly signed Mike Tauchman. Slater employed his limited skill-set for three different clubs last season as he continues to be a disciplined hitter who can earn walks while also generating a high volume of strikeouts. 2021 was Slater's last true season of fantasy viability in mixed leagues, while 2022 was the last time he had value even in mono leagues. The open tryout situation in Chicago creates an opportunity for anyone who shows they can hit, so perhaps Slater can extrapolate pieces of what made him good in 2021 and 2022, and for some of 2023, and play that into some value for deeper AL-Only leagues in 2025.
Slater was limited to just 90 plate appearances in the first half last season due to a pair of hamstring injuries. He later had arthroscopic surgery on his right elbow just after the season to remove a bone spur which apparently had been an issue for a couple years. In between the injuries and surgery Slater was his usual productive self against left-handed pitching, slashing .288/.361/.439 with four homers in 147 plate appearances. He started just seven games versus righties and collected a .619 OPS. Slater's role as short-side platoon specialist is very defined at this point and it's unlikely to change under new manager Bob Melvin. The 31-year-old is good enough at the role to have some deep-league fantasy value, but he's simply not going to play enough to be useful in shallower leagues.
Slater filled his usual platoon against southpaw role, but improved numbers against righthanders fueled a career-high number of plate appearances, albeit in fewer games than 2021 since Slater incurred a couple of shirt IL stints. His power dropped, commensurate with the hitting environment, but the rest of Slater's underlying metrics carried over from the prior season. With Mitch Haniger signed as a free agent, Slater is again destined for short side of the platoon work, spelling Joc Pederson and sometimes Mike Yastrzemski along with some time at designated hitter. Slater's ability to collect double-digit steals in a part-time capacity has some mixed league appeal, but more on a fill in basis when it is clear he'll be on the field frequently during that transaction period.
Slater helped propel the Giants to the playoff by filling the short side a platoon in the outfield. His double-digit home runs and stolen bases make it seems like he could benefit from more playing time. The deal is that an extreme platoon split will limit his upside. In his career (843 PA), he's struggled against righties (.633 OPS, .853 OPS against lefties). Those struggles didn't end in 2021 with a .894 OPS vs. LHP and just a .497 vs. RHP. Nothing in his profile points to his struggles against lefties going away. His fantasy value comes down to the league type. If the league allows daily moves, he can be started when there is a lefty on the mound, and benched the rest of the time. In a weekly league, he's waiver wire fodder, appealing primarily in those one or two weeks when the Giants are facing five or more lefties. Don't get sucked into doubling his 2021 season.
Groin and elbow issues limited Slater to just 31 games last season, but he was impressive when available, hitting .282/.408/.506 with five homers and eight steals. That's quite a big change from what the 28-year-old showed in his first three partial seasons, when he posted a .254/.335/.368 line in 176 contests, looking firmly like a fourth outfielder. His improvements may have come in a small sample, but they were backed up by strong peripherals, with his .305 xBA and .542 xSLG suggesting he may have even underachieved. His 14.1% barrel rate, 15.4 BB% and 21.2 K% were all career bests. A return to previous form wouldn't be a huge surprise given how brief his breakout was, but if he keeps making considerably more contact that he had in the past while hitting the ball harder than ever, he'll remain a capable everyday starter at minimum and a potential draft-day bargain.
Slater split time between the minor leagues -- where he hit .308 in 240 at-bats -- and the majors last season. With the Giants, he posted a .238 average and a modest five home runs in 192 plate appearances. Nonetheless, Slater showed some signs of being a capable big-league hitter. Most notably, his 11.5 BB% was well above league average, and his 45.0% hard-hit rate was a sizable jump over his previous two stints in the majors. Of course, hitting the ball hard is only relevant if a player is able to put the ball in play, and that has been a struggle for Slater throughout his time with San Francisco. He posted a 30.7 K% for the second consecutive season in 2019, dampening much of the progress he made at the plate. Slater's defensive versatility is an asset, but given his penchant for striking out and less-than-stellar production through 176 career big-league games, a roster spot for 2020 is not guaranteed.
Slater's sophomore season was largely a forgettable one, as he managed a mediocre.251/.333/.307 line in 74 big-league appearances. His strikeout rate jumped nearly eight percentage points to 30.7%, while his slugging percentage fell by 95 points. It took a .377 BABIP to get him up to his unimpressive batting line, which doesn't bode well for a player who is limited to first base and the outfield corners, defensively. Those who want to hold out optimism for the 26-year-old's future can point to his .319/.391/.513 line over parts of three seasons with Triple-A Sacramento, but he just hasn't been able to maintain anything close to that level of performance against big-league pitching. The rebuilding Giants should have plenty of playing time for players like Slater, so he'll likely be given another chance to prove himself at some point.
Slater didn't make a ton of noise in his 34-game debut, but he was perfectly adequate at the dish. After getting the callup on June 2, he hit .282 with a league-average 100 wRC+ in 127 plate appearances. A torn adductor muscle in his right hip cost Slater most of the second half. He returned late in September, but only made five appearances before landing back on the shelf with a sports hernia, which required surgery. Slater's control of the strike zone is a little shaky (22.8 percent strikeout rate last year, 6.3 percent walk rate), and his home park mitigates what power he has, but he's just 25 and should at least be afforded chances against lefties to begin 2018. He can play all three outfield positions and can even man the infield in a pinch. As a reserve in NL-only, Slater makes some sense, but he will need to show more and work himself in to a bigger role before he pops up on the mixed-league radar.

Latest Fantasy Rumors
Yankees interested in reunion
OFFree Agent
February 3, 2026
The Yankees have Slater "on their list" as they seek a right-handed-hitting outfielder, Jon Heyman of the New York Post reports.
Analysis
Slater went just 3-for-25 at the plate in 14 regular-season games last season after the Yankees acquired him at the trade deadline, missing a chunk of time down the stretch with a strained hamstring. However, the 33-year-old boasts a career .267/.357/.430 batting line versus left-handers, which still makes him a fit for the Yankees' bench.
