Luke Weaver entered free agency after pitching to a 3.62 ERA in 64 2/3 innings this year as one of the Yankees’ top relievers. He struck out 27.5% of hitters against a 7.6% walk rate and ranked 38th among qualified relievers by K-BB rate. That was a slight step down from his excellent 2024 campaign, when he posted a 2.89 ERA and a 23.3% K-BB rate, which ranked 19th among 169 qualified relievers. Still, he was generally productive during his two years in the Bronx and figures to do well in free agency.
Weaver’s performance noticeably declined following a stint on the injured list in June for a left hamstring strain. After posting a 2.31 ERA in 24 appearances through the end of May, that number jumped to 5.31 in 40 appearances post-injury. Meanwhile, his groundball rate declined from 36.4% in 2024 to just 27.5% this year, which put Weaver in the first percentile according to Statcast. His fly ball rate also jumped nearly ten points to a career-high 56.3%, well above the league average of 38.1% for relievers.
Still, teams will be interested in his strikeout ability and recent pedigree as a high-leverage arm, as well as his openness to becoming a starter. We at MLBTR ranked Weaver at No. 41 on our Top 50 Free Agents list and projected him for a two-year, $18MM contract. Which team will take the plunge? Let’s take a look at some of the options:
Diamondbacks
Arizona’s relievers ranked 28th in the league with a combined -0.3 fWAR in 2025, and their 4.82 ERA ranked 27th. While Shelby Miller and Andrew Saalfrank posted ERAs under 2.00 in 36 1/3 and 29 innings respectively, most of the other relievers ranged from unspectacular to below average. Jalen Beeks was the only qualified reliever of the bunch, posting a 3.74 ERA in 55 1/3 innings. The bullpen’s 11.2% K-BB rate was higher than only the Nationals and Rockies. Weaver, who pitched for the Diamondbacks from 2019-22, would help immensely with the strikeouts, though the hitter-friendly environment of Chase Field may be a less-than-ideal fit given his now-extreme fly ball tendencies. On the other hand, the club is known to be in the market for starting pitching, so it’s possible they could sign Weaver and give him a chance in the rotation.
Mariners
The Mariners’ bullpen was middle-of-the-pack in 2025, with a 3.2 fWAR that tied for 17th in the league and a 3.72 ERA that ranked 9th-best (albeit with half their games in the pitcher-friendly T-Mobile Park). Andrés Muñoz, Gabe Speier, and Matt Brash all posted ERAs under 2.70 with strong peripheral stats, including strikeout rates above 29.0%. Beyond those three and Eduard Bazardo, the unit could use some more depth. Carlos Vargas pitched 77 innings in 2025 but was worth -0.6 fWAR thanks to a meager 16.3% strikeout rate and weak peripherals. Trent Thornton, Collin Snider, and Casey Legumina covered 117 1/3 innings in total, but all three had ERAs over 4.50. Reuniting with Weaver (he pitched 13 1/3 innings for Seattle in 2023) would improve the bullpen’s strikeout ability, while the spacious T-Mobile Park could provide cover for his fly ball tendencies.
Orioles
Baltimore’s bullpen ranked 23rd with a collective 1.9 fWAR and 25th with a 4.57 ERA. Keegan Akin and Yennier Cano were the team’s only qualified relievers, and Akin was worth -0.6 fWAR while Cano had an ERA of 5.11 (albeit with an xERA of 3.59). Seranthony Dominguez had a 3.24 ERA and a 30.9% strikeout rate in 41 2/3 innings, but he was traded to the Blue Jays at the deadline. Felix Bautista had a 35.2% strikeout rate and a 50.7% groundball rate in 34 2/3 innings before undergoing surgery in August to repair a torn rotator cuff and a torn labrum. At best, he won’t be back until September 2026. Baltimore is known to be looking for an experienced closer. A Weaver signing could make sense, given his track record of success in the AL East.
Cubs
Cubs’ relievers were 19th in the league with a combined 3.1 fWAR and tied for 14th with a 22.7% strikeout rate. Brad Keller, Caleb Thielbar, Daniel Palencia, and Drew Pomeranz led the unit in innings pitched and all had ERAs under 3.00, but Keller, Thielbar, and Pomeranz are now free agents. Andrew Kittredge posted a well-above-average 35.4% K-BB rate in 21 2/3 innings after being acquired at the deadline, but he was traded back to the Orioles in November. Beyond those pitchers, the club saw Chris Flexen, Ryan Pressly, and Porter Hodge combine for 114 innings. Flexen had a solid ERA but ugly peripheral numbers and is now a free agent. Pressly was underwhelming in his age-36 season and is also a free agent, while Hodge posted a 6.27 ERA and walked 12.2% of hitters faced. A Weaver signing would add an experienced high-leverage arm behind Palencia while still leaving room for additions elsewhere.
