2025 Fantasy Outlook

In his first full season with the Yankees, Weaver posted a 2.89 ERA and 0.93 WHIP across 84 innings - a stark contrast from the 5.85 ERA and 1.51 WHIP he accumulated over the previous four years. The 9-year veteran fully transitioned to a reliever, making a career-high 62 appearances as a Swiss Army knife out of New York's pen. Weaver's transition coincided with a pitch mix adjustment, ditching his slider and sweeper completely while throwing fewer knuckle curves - from 267 pitches thrown in 2023 to just 17. By pitching in shorter stints, Weaver added velocity on his fastball (95.7 mph on average) and changeup (88.6 mph) with great results, the latter generating a 48 percent whiff rate that was tops in the league for that pitch type. His success made it a no-brainer for the Yankees to exercise his $2.5 million club option for 2025. While Weaver spent time as the Yankees' closer during the 2024 playoffs, he'll likely revert back to setup duties with Devin Williams now in tow. Read Past Outlooks

PNew York Yankees

May 14, 2025

Weaver struck out three in a perfect inning to earn the save in Wednesday's 3-2 win over the Mariners.

ANALYSIS
Weaver has bounced back from his blown save May 5 versus the Padres with 4.2 scoreless innings over his last three appearances. This was his first save in that span, as the Yankees hadn't produced a save situation in over a week. The right-hander continues to post elite numbers with a 0.45 ERA, 0.60 WHIP and 22:6 K:BB across 20 innings while adding four saves and six holds this season. Weaver is capable of working multiple innings, so he may not get every save chance, but he's answered the call nearly every time he's taken the mound this season.

Weaver has seen action with five teams across the past two seasons, working mostly as a reliever in 2022 and a starter in 2023. The right-hander struggled in both campaigns with a combined 6.44 ERA in 55 appearances (26 starts), though he was still able to land a one-year, $2 million contract with the Yankees for 2024. Weaver is unlikely to make the Opening Day rotation if everyone remains healthy, but he'll likely be called upon for some starts at some point. He could have some streaming value if he excels as a swingman, but his inconsistent track record doesn't offer much fantasy upside.

Weaver transitioned to a relief role for much of 2022, but his performance continued to underwhelm. Over 35.2 innings between Arizona and Kansas City, the right-hander posted a 6.56 ERA and a career-worst 1.82 WHIP. Even the pitching desperate Royals couldn't tolerate that, waiving Weaver in October. The Mariners claimed him but declined to tender him a contract for 2023, so he is a free agent this offseason. He's three years removed from a viable season in any role, and it's very possible he has to settle for a minor-league deal or a contract overseas to continue his career. On the bright side, his 2.56 FIP from last season suggests he was cosmically unlucky, though it also came in a relatively small sample compared to previous years.

Weaver was one of the worst starters in baseball during the shortened 2020 campaign with a 1-9 record and 6.58 ERA, but he rebounded last season to post a respectable 4.25 ERA, 1.19 WHIP and 62:20 K:BB over 65.2 innings. The 28-year-old missed over three months with a rotator cuff injury but returned for the final month of the season and pitched well down the stretch. Weaver should work at the back end of Arizona's rotation and could be a streaming option in deeper leagues if he can continue the upward trend from 2021.

Weaver was the only pitcher in MLB tagged with nine losses despite making only 12 starts during the shortened season, and the rest of his numbers (6.58 ERA and 1.56 WHIP) also weren't pretty. It's quite the contrast to 2019, when the right-hander dazzled with a 2.94 ERA and 1.07 WHIP in 12 starts before going down with injury. His flyball rate increased more than 10 percentage points to 48.4%, while his HR/9 more than doubled to 1.74. However, the 4.66 FIP indicates he also didn't receive much help from his defense. Weaver remains a strong bet to retain a rotation spot to begin 2021, and he's a reasonable buy-low candidate following the rough campaign considering his workable strikeout and walk rates (23.3% and 7.6%, respectively).

Weaver was pitching extremely well in 2019 before he went down in late May with forearm tightness, which held him out for all but two innings the rest of the season. Weaver emphasized his cutter in 2019 to give him a more effective third pitch, and saw a resurgence in his strikeout rate and a stat line that looked a lot closer to his 2017 promise than his 2018 disappointment. Those worried about the forearm issue should take solace in watching what Tyler Glasnow did last year. Both pitchers were shut down with similar issues, yet Glasnow came back late in the season and was throwing darts in the postseason as if he hadn't missed a beat. Weaver's lack of work after the injury may hold down his cost on draft day, and where you take him should depend on your appetite for risks. The move to Arizona was a good one for him, and he was taking a positive step forward before the injury.

Drafted just outside the top 100 last spring, Weaver was one of 2018's bigger disappointments, as he ended the season in a mop-up role. It's probably too early to completely write off the 25-year-old right-hander, who was sent to Arizona as the headliner in the Paul Goldschmidt trade. Weaver's first-pitch strike rate along with his swinging-strike rate were virtually the same as the previous season. However, in 2017 Weaver posted a 28.6% strikeout rate, compared to a 19.9% mark last season, perhaps because the book was out on his shallow repertoire. Whiffs aside, Weaver's control and command slid last season, as he walked more while allowing more homers. He still lacks a quality third pitch (opposing batters slugged .589 against his curveball), and his top two pitches (fastball, changeup) were not as dominant as they needed to be for him to have sustainable success. His upside is limited to a low-innings mid-rotation starter until that pitch mix improves.

Say what you will about a "soft" schedule for Weaver; he was excellent in 2017. The right-hander posted a 2.05 ERA over his first 11 starts, and while a couple of poor performances at the end of the year inflated his overall numbers, Weaver finished with a 3.17 FIP and 2.93 xFIP over 60.1 innings at the big-league level. He averaged 10.7 K/9 and just 2.5 BB/9 -- he had the 28th-best K-BB percentage among 274 pitchers with at least 60 innings. Weaver did well to keep the ball on the ground (49.4 percent GB%) and limit hard contact, resulting in a .287 xwOBA. He is still primarily a fastball-changeup pitcher, but the changeup is a dominant pitch, and his curveball is coming along. The only real concern with Weaver is his workload. He totaled just 138 innings between the majors and minors last year, his highest total as a professional, after throwing 119.1 combined frames in 2016.

Weaver got his first taste of the majors at the latter end of the 2016 season. He pieced together a few rough outings and ended the year with a 5.70 ERA and 1.60 WHIP that was built over nine games (36.1 innings). Lefties were particularly tough for Weaver and they went 23-for-69 (.377) against the 23-year-old. Fortunately for the club, he showed signs of promise and produced a 27 percent strikeout rate in that time. Weaver has shown he's a capable starter in the minors, as he dominated his 12 starts at Double-A Springfield in 2016. Heading into 2017, the Cardinals may have Weaver compete for a spot at the back of their rotation, or could opt to use him from the bullpen as they did at the end of 2016. However, the most likely course of action will be to send him to Triple-A Memphis, where he's only appeared in one game to this point, to keep developing his breaking pitches until he's deemed MLB-ready.

Weaver appears to be a third pitch away from being a No. 3 starter, thanks to a low-90s fastball and a filthy changeup that will work as an out pitch at the highest level. That combination was enough for him to breeze through the pitcher-friendly Florida State League with a 1.62 ERA, 1.11 WHIP, and 88 strikeouts in 105.1 innings. Those numbers rightfully put him squarely on the radar of dynasty league owners, but most reports suggest his curveball lags way behind the rest of his arsenal. Without that third pitch, there is not much to see here, so Weaver should still be seen as a work in progress. Fortunately he is in a competent organization, and at least two years away from the big leagues, so it is OK that he is not a finished product. He will head to Double-A Springfield in 2016, where it should become fairly obvious if he has improved his breaking ball.

The 27th overall selection out of Florida State in the 2014 amateur draft, Weaver is expected to work his way through the Cardinals' system rather quickly and could be competing for a roster spot as soon as 2016. Weaver was only able to log 9.1 professional innings with the club's rookie and High-A affiliates, getting six starts and striking out 12. Expect Weaver to start 2015 in either Low-A or High-A for the Cardinals, possibly finishing the season in Double-A if he pitches well. Weaver has drawn praise as one of the lowest risk pitchers drafted. Fantasy owners still shouldn't expect anything on the MLB level until 2016, with 2017 being the most likely scenario.
