Bailey Ober’s path back to dominance is getting narrower, and the biggest reason is sitting on the left side of the plate.
The Twins right-hander has been able to keep taking the ball and working into games even while his fastball has backed up. He’s averaging 88.3 mph on the pitch, down 2.0 mph from this year and 4.1 mph since his debut with Minnesota in 2021.
The raw stuff isn’t as loud as it once was, but Ober has still found ways to give his team length. He has gone at least five innings in 16 of his 21 starts, and in half of them he’s reached six or more.
The strikeout totals tell a different story. Across those 21 starts, Ober has topped seven strikeouts only four times, including April 19 against the Cincinnati Reds, when he punched out 10 in 6 ⅓ innings. That kind of swing-and-miss outing has been too rare, and the issue becomes even more obvious when left-handed hitters are involved.
Historically, Ober hasn’t had a glaring platoon split in the majors. Left-handed batters have posted a .708 OPS against him, while right-handers have sat at .725.
The home run rates are close too, at 3.8% and 4.3%. This season, though, the numbers have moved hard in the wrong direction.
Left-handed hitters have hit twice as many home runs off Ober as he has allowed this year, and the damage gets worse away from home, where his HR% climbs to 5.0. Their OPS against him rises to .879 there, the highest mark in any of the splits.
The drop in velocity has also shown up in his ability to miss bats. Ober’s strikeout rate against left-handed hitters is 4.5 K/9, the second-lowest in the majors this season. Only Arizona Diamondbacks right-hander Zac Gallen, at 4.3, has struck out fewer left-handed batters.
That’s a brutal profile for any starter trying to hold down a rotation spot, but Ober’s last three outings offered a more encouraging look. Against the Atlanta Braves, San Diego Padres and Chicago White Sox, he worked 14 ⅓ innings, allowed four earned runs, struck out 12 and walked six. He averaged 87 pitches per start, never gave up more than two earned runs and got through five innings in his last two trips.
There is at least one area where he has made progress. Ober has cut his BABIP against left-handers from .282 last year to .233 this season. That doesn’t erase the bigger problem, especially with his .495 slugging allowed against lefties standing as the worst of his career, but it does leave room for adjustment.
The deeper concern is contact. Ober’s Whiff% against left-handed batters has fallen from 27.2% in 2024 to 15.7% this season, the lowest point of his career. Once the swing-and-miss disappears, everything else starts to unravel.
That’s why the Twins are watching this so closely. With Joe Ryan out because of injury, they expect Ober and Taj Bradley to help steer the rotation as they try to stay in the postseason race.
Soon enough, we’ll know whether Ober’s recent success against lineups loaded with left-handed bats was the start of something real, or just a brief fix to a much bigger problem.

Twins Move On From Kyler Fedko In Painful Roster Twist
September roster moves brought a tough break for Kyler Fedko, whose name had been one of the more interesting ones to watch as the Twins navigated the final stretch of roster expansion. Minnesota designated the outfielder for assignment while officially adding infielder Ben Ross to the 40-man roster, and the club also recalled right-hander Garrett Acton from Triple-A as part of its September call-ups.
Fedkos situation is complicated by the severe knee injury that altered his path, and the injury waiver rules now push him toward release. From there, the door is not necessarily closed, since he could potentially re-sign with Minnesota or land elsewhere, but for now the Twins have had to make the kind of roster decision that cuts deeper than most.

Twins September Call-Ups Raise A Bigger Question About This Playoff Push
The Twins are using Septembers roster expansion to add a little more depth where the stretch run tends to get thin. Right-hander Garrett Acton, recently activated from the injured list after arriving from the Miami Marlins, gives the bullpen another arm, while utilityman Ben Ross arrives with the kind of minor league track record that can help a contender squeeze value out of matchups, especially against left-handed pitching.
For a club still hanging around the postseason race, the moves fit the moment: protect the pitching staff, widen the bench and give the lineup a few more ways to tilt an inning. What makes the call-ups more interesting is what they suggest about how the Twins want to navigate the final weeks, with bullpen depth and platoon flexibility taking on a little extra weight as the games get bigger.

Twins Triple-A Lineup Is Suddenly Chasing An Even Bigger Record
The power surge in St. Paul has turned the Twins Triple-A affiliate into one of the loudest lineups in the minors. The Saints already had enough thump to make a statement, but their latest pair of long balls pushed them past the International League single-season home run record, with Kalai Rosario providing the tie and Cody Morissette delivering the one that moved them into new territory.
What makes the chase even more interesting from a Minnesota perspective is that this has become more than a one-player feat. The Saints now have 12 players with at least 10 home runs, a spread-out attack that has kept the lineup dangerous all season and left them within reach of the all-time minor league single-season home run mark held by El Paso. For a Twins organization that values depth and internal options, this kind of production is hard to ignore. [Read more 🡒]
