The Twins have already moved Chris Paddack and Jhoan Duran, but they’re expected to remain active on the selling front right up until this afternoon’s deadline. Ken Rosenthal of The Athletic reports that as of last night, Minnesota was far more focused on negotiations pertaining to relievers Danny Coulombe and Brock Stewart than on anything involving top starter Joe Ryan, who still seems like a long shot to move. Meanwhile, Bobby Nightengale of the Minneapolis Star-Tribune reports that the Twins have had about six clubs looking into utilityman Willi Castro and haven’t ruled out trading righty Griffin Jax even after moving Duran — but the price remains extremely high.
Coulombe is one of the most straightforward trade candidates on the market. He’s a rental reliever on a clear seller who’s having a terrific season while playing on a low-cost contract. He signed a one-year, $3MM deal to return to the Twins in the offseason and has rewarded that investment with a 1.16 ERA, 25.4% strikeout rate and 7.4% walk rate in 31 innings. He’s thrived versus lefties and righties alike. It’d be a surprise if Coulombe somehow wasn’t traded before today’s deadline.
Stewart, 33, isn’t necessarily as likely to go but could have some sneaky value. He’s 33 years old and has had plenty of injury concerns in his career, including Tommy John surgery while with the Dodgers and shoulder surgery with the Twins just last year.
That said, when Stewart has been healthy in Minnesota, he’s been excellent. He’s pitched 77 1/3 innings since landing with the Twins on a minor league deal in the 2022-23 offseason, and in that time he’s posted a 2.33 ERA with a huge 31.7% strikeout rate and a 9.5% walk rate. Stewart is sitting 96.1 mph on his four-seamer this year and has run his heater up to 100 mph at times. He’s sporting an outstanding 15.1% swinging-strike rate and has a massive 16.5% mark over the past three seasons combined.
The Twins don’t need to move Stewart, who’s earning just $870K this year and has two seasons of club control remaining. However, as a reliever in his mid-30s who was originally added on a minor league deal, there’s a bit of a “found money” aspect to the hard-throwing righty. His lengthy history of arm troubles also surely has to tempt the Twins to sell high right now, while he’s performing well. Stewart isn’t going to garner headlines like Duran, Jax and other controllable arms on the relief market (e.g. David Bednar, Mason Miller), but he’s quietly posted high-end results at near league-minimum salary.
Castro feels like another surefire trade candidate today. Like Coulombe and Stewart, he was originally signed by the Twins on a minor league deal before revitalizing his career in Minnesota. He’s hitting .245/.335/.407 with 10 homers and nine steals in 344 plate appearances on the season and has slashed .250/.335/.398 in his three years as a Twin.
The switch-hitting Castro is earning $6.4MM in 2025 and is a free agent at season’s end. He’s a 28-year-old with average power and above-average speed who can handle just about any position on the field. He’s played second base, third base, shortstop and all three outfield spots in 2025, though he’s stretched defensively at shortstop or in center field and is more of a backup option than a candidate for regular playing time at those positions. Given his versatility, Castro would deepen any contending club’s bench, and he’d be a starting option for several playoff contenders. The Mariners, Yankees and Astros have all shown interest this month, though the first two of those teams have obviously added some new infield options already, which could impact their current level of interest in Castro.
With Duran out the door and Coulombe and Stewart possibly following him, a trade of Jax would really deplete the Twins’ bullpen. The Twins will remain open to the idea, it seems, but they’re not likely to deviate from their asking price. They’ve been seeking multiple top-100 prospects for both Duran and Jax. They secured a strong return for Duran (catching prospect Eduardo Tait and MLB-ready starter Mick Abel) and will hold out for the same with regard to Jax.
The 31-year-old Jax is a former third-round pick. A look at his 4.50 ERA isn’t going to turn any heads, but the right-hander posted a 2.03 ERA last season and misses bats more than nearly any pitcher in the game. His 36.4% strikeout rate is fifth in all of baseball among the 293 pitchers (starter and relievers alike) with at least 40 innings pitched this season. His 19.5% swinging-strike rate sits third, trailing only Josh Hader and Aroldis Chapman. Jax’s 1.97 SIERA ranks second in baseball, trailing only the 1.96 mark of breakout Giants reliever Randy Rodriguez.
Jax is under club control for two more years beyond the current season. He had a brutal outing yesterday — three runs without recording an out — but even including that tough day has a 3.08 ERA and 1.49 FIP in 38 innings dating back to late April. He’s the clear favorite to close games for the Twins moving forward. The Yankees are among the clubs looking into Jax, Jon Heyman of the New York Post suggests, and the Mariners have been in the mix as well.
