2024 Fantasy Outlook
Jax led Twins relievers with 71 appearances and 23 holds last season as the team's primary setup man. The 29-year-old racked up 10 losses to lead all relievers, but his ratios and underlying metrics were solid. Jax's 3.3 barrel percentage allowed was in the 97th percentile, while his hard-hit percentage, average exit velocity and 56.8 percent ground ball rate were all well above-average. His 2.86 xERA was a full point better than his 3.86 ERA, which shows there's room for improvement in that category. Expect Jax to rack up 20-plus holds and a handful of ancillary saves again in 2024.

Move to rotation not ruled out
Twins bench coach Jayce Tingler indicated in a recent interview that the team is open to the possibility of moving Jax into the rotation, Mike Ferrin of MLB Network Radio reports.
ANALYSIS
Jax came up through the minors as a starting pitcher and made 14 starts for the Twins in 2021, posting a 6.10 ERA. He's since turned into a lockdown reliever, most recently collecting a 2.03 ERA and 95:15 K:BB over 71 innings this season. With a five-pitch mix and 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.

Past Fantasy Outlooks
2023
2022
2021
After making 14 starts during his rookie 2021 season, Jax transitioned to full-time relief last year. He didn't make the Twins' Opening Day roster, but was recalled a few days after the season started and quickly settled into his new multi-inning role out of the bullpen. Increased velocity (+2.8 mph on average) and a pitch mix adjustment followed the role change, as Jax's slider (48% usage) replaced his 4-seamer (34%) as his primary offering. The 28-year-old improved both his strikeout (26.9%) and walk (6.9%) rates with a 78:20 K:BB ratio over 72.1 innings. He also induced grounders at a 47.3% rate to create a profile that should be on deeper mixed league radars regardless of role. Jax quickly ascended Minnesota's leverage ladder and became one of their primary setup men, tying for the team lead with 18 holds. Expect plenty of volume - Jax was 11th among qualified relievers with 72.1 innings - along with decent ratios and potentially even saves in 2023.

Latest Fantasy Rumors
Trade possible
The Twins could listen to trade offers for Jax this offseason, Aaron Gleeman of The Athletic reports.
ANALYSIS
As Gleeman writes, trading Jax now would make sense only if the Twins get an offer they feel they can't refuse. The righty will see his salary rise in 2025 in his first year of arbitration, but he is under team control through the 2027 season. Jax held a 2.03 ERA and 95:15 K:BB across 71 innings in 2024 and is slated to be a high-leverage reliever again next season, provided the Twins don't move him into the rotation.
