2026 Fantasy Outlook
Jax did not record any saves in 2025, but he finished eighth among relievers with 28 holds and sixth with a career-high 99 strikeouts. His sweeper was responsible for a majority of those strikeouts (59), as Jax's 46.5 whiff percentage was best in the league for that pitch type. The right-hander's 92.3 mph changeup was equally as devastating, also inducing a 46.5 whiff percentage, though he curiously tossed fewer of those following a mid-season trade to Tampa Bay. Unfortunately, Jax wasn't successful with his high-velocity offerings, as his fastball (.320 BA, .620 SLG) and sinker (.333 BA, .524 SLG) were crushed by opposing hitters. Same for the occasional cutter that he tinkered with to left-handed batters. Now that Jax is with the Rays, he might tinker with his pitch mix even more than years past, though his sweeper and changeup should remain the focus of his arsenal. Jax has a clear path to saves in 2026, though Kevin Cash's plans for the ninth inning are currently unknown. Read Past Outlooks
Signed a one-year, $3.57 million contract with the Rays in January of 2026.
Unlucky to lose Saturday
Jax (1-5) allowed one unearned run on five hits and struck out five without walking a batter over five innings, taking the loss Saturday versus the Angels.
Analysis
The Angels were able to run up the score against the Rays' bullpen, leaving Jax with an unfortunate loss despite a strong showing. He threw 44 of 63 pitches for strikes and completed five frames for the second start in a row. For the season, Jax has a 3.68 ERA, 1.36 WHIP and 41:18 K:BB over 44 innings across 20 appearances (nine starts). The right-hander is still being built up carefully after opening the campaign in the bullpen, which makes it difficult for him to pitch long enough to qualify for wins. His next outing is projected to be at home versus the Nationals.

Past Fantasy Outlooks
2025
2024
2023
2022
2021
Jax broke out as a lockdown reliever in 2024, posting career-best marks across multiple categories including a 2.03 ERA, 0.87 WHIP, 95 strikeouts, 10 saves and 24 holds. The 29-year-old significantly improved his strikeout rate (34.4 percent) by nearly 10 percentage points - his sweeper and changeup headlining his five-pitch aresenal with 45 percent or better whiff rates. Jax's 37.8 percent overall whiff rate was a 98th percentile metric. The Twins recently indicated they're open to the possibility of moving Jax to the starting rotation. The right-hander came up through the minors as a starter and made 14 starts for the Twins in 2021, posting a 6.10 ERA. Given his past starting experience, Jax would seem more equipped for a shift to the rotation than most relievers. The question is whether the uptick in stuff since his move to relief would translate back to a starting role.

Latest Fantasy Rumors
Twins still fielding offers
The Twins remain in trade talks regarding Jax even after dealing Jhoan Duran, Ken Rosenthal of The Athletic reports.
Analysis
Jax is currently in line to take over as the Twins' closer following the departure of Duran, but trade talks involving Jax have "increased" Thursday, per Rosenthal. It would take a haul in order to pry him from the Twins, as Jax boasts a 35.2 percent strikeout rate over the last two seasons and is under team control through 2027.
