MLB Trade Rumors

The Rockies, more open to dealing at this year’s deadline than in seasons past, have been open to offers on controllable young relievers in their bullpen. The Rox have several power arms who could appeal to bullpen-needy contenders, and two teams that have been eyeing them recently are the Rangers (per Evan Grant of the Dallas Morning News) and Mariners (per Daniel Kramer of MLB.com).

Grant reports that the Rockies are under the impression that right-handers Jake Bird, Victor Vodnik and Tyler Kinley are all available via trade. As a veteran in the final guaranteed season of his contract, Kinley is a fairly straightforward trade candidate. But Bird, who’s controlled three years beyond the current season, and especially Vodnik, who’s controlled for an additional four years, stand as the types of player Colorado wouldn’t even consider moving at prior trade deadlines.

Kinley, 34, is making $3MM in 2025 and has a $5MM club option with a $750K buyout. He’s sporting an ugly 5.66 ERA but more appealing secondary marks. The 6’4″ righty is averaging 95.2 mph on his four-seamer but uses his slider as his primary offering (60.1%), which has surely contributed to a hefty 14% swinging-strike rate. That’s a well above-average mark and could portend an uptick in Kinley’s 23.8% strikeout rate, which is only a bit better than average. Kinley’s 12.6% walk rate needs work, but he’s shown better command in the past. Metrics like FIP (4.14) and SIERA (4.15) both feel he’s been better than his ERA, and other clubs might be intrigued to see what he could do with more analytical input than the Rockies provide.

Bird, 29, was excellent through the end of June but has had a brutal month in July. He’s been rocked for 15 runs (14 earned) in just 6 2/3 innings since the calendar flipped, ballooning his once-terrific 2.63 ERA all the way to 4.73. He has roughly average velocity but makes good use of a sinker/slider/curveball repertoire to miss bats and keep the ball on the ground at above-average levels. In 53 1/3 innings — Bird frequently works more than one inning per outing — he’s fanned 26.3% of his opponents against a 9.7% walk rate. Bird’s 48% ground-ball rate is well above average, and he’s done a nice job avoiding home runs both in 2025 (0.84 HR/9) and in his career (0.90).

The 25-year-old Vodnik would be valued most highly of the trio mentioned by Grant. He’s in just his second big league season and is sporting a tidy 3.19 ERA with an above-average 23.9% strikeout rate and a massive 56.6% ground-ball rate in 31 frames. Vodnik averages a blistering 98.6 mph on his fastball and just under 92 mph on his “changeup.” However, Vodnik doesn’t quite miss bats at the level one might expect from someone with such a powerful arsenal. The results have been strong nonetheless, though Vodnik’s 4.12 FIP and 4.11 SIERA (driven by his shaky command) point to some potential regression.

Vodnik and Bird, in particular, seem like they’d hold appeal to a Rangers club that has some reluctance to exceed the luxury tax threshold. Neither has reached arbitration yet, so neither would add to the club’s luxury obligations. Kinley would have just $951K left on his contract by the time the deadline rolls around, though the $750K buyout on his 2026 option would also come into play.

Bird is also on the Mariners’ radar, per Kramer, who notes that Seattle has “heavily” scouted him and bullpen-mates Juan Mejia and Seth Halvorsen. Mejia is a particularly obscure trade candidate, given that he just made his MLB debut earlier this year. He’s pitched 36 innings and logged a 4.50 ERA but with a 3.78 FIP and 3.60 SIERA. He’s set down 23.7% of his opponents on strikes and walked 8.6% of the hitters he’s faced.

Mejia is a pure two-pitch reliever with a four-seamer that averages 96.2 mph and a slider sitting 82.9 mph. He’d be controllable for a full six years beyond the current season and is in the second of two minor league option years. That’d give Seattle plenty of long-term control and flexibility.

Halvorsen, 25, is arguably the most appealing of the whole group. His 4.99 ERA is pedestrian, but he’s averaging 100 mph on his four-seamer, inducing chases off the plate at an above-average rate and sporting a 13.2% swinging-strike rate. The flamethrowing young righty has punched out just 20.9% of his opponents but fanned batters at a 28.9% rate during last year’s debut (albeit in a smaller sample of innings). His 11.6% walk rate is too high, but his 54.4% grounder rate is excellent.

Halvorsen only briefly got a look late last season and hasn’t been optioned since first being selected to the big leagues. As such, he has a full slate of three option years. He’s controlled for five more years beyond the current season. Pitchers who average 100 mph or better and keep the ball on the ground at such high rates are rare breeds, and Halvorsen’s chase rate, swinging-strike rate, minor league numbers and 2024 results all suggest there could be more strikeouts in the tank as well. His command has never been great, and that’ll be the challenge for the Rockies or another club to unlock, but the raw tools in Halvorsen’s arsenal are tantalizing.

Whether the Rockies actually bite the bullet and trade any of their controllable relievers is an open question, but there’s a relatively limited supply of relievers controlled beyond the current season and a large number of teams hoping to acquire such pitchers. Beyond the Rangers and Mariners, each of the Phillies, Tigers, Yankees, Dodgers, Mets and Cubs have been linked to relievers with multiple years of club control. One long-shot possibility, Cleveland’s Emmanuel Clase, was removed from consideration earlier this week when he was placed on administrative leave amid MLB’s ongoing gambling investigation.

While there are plenty of bullpen arms available on the market, many of them (e.g. Ryan Helsley, Raisel Iglesias) are free agents at season’s end. Teams like the Pirates (David Bednar, Dennis Santana), Guardians (Cade Smith) and particularly the Twins (Jhoan Duran, Griffin Jax) have set lofty asking prices on the bullpen arms they control beyond the current season. The Rox will surely have a hefty asking price on relievers like Vodnik and Halvorsen, but the demand for controllable bullpen help could present them with an opportunity to provide a jolt to a weak farm system.
