Ottoneu: Jake’s 2026 Keep or Cut Decisions at SP

The Ottoneu keeper deadline is quickly approaching. There’s less than a month left to make your roster decisions before the January 31 cut deadline. I’m going through a handful of difficult keep or cut decisions at every position group to give you a transparent look at my decision making process and hopefully help you with theses specific cases for these specific players. I’ve already covered hitters in three separate articles — corner infielders, middle infielders, and outfielders — now I’m wrapping everything by covering three starting pitchers.

Kodai Senga, SP
Salary: $16, $17
Average Salary: $18
2025 P/G: 4.33
Projected 2026 P/G: 4.16

I’m not sure the Mets know what to do with Kodai Senga so I wouldn’t blame you if you didn’t know what to do with him on your fantasy squad. Injuries cost him nearly all of 2024 and a hamstring injury in June derailed his season a year later. Before that injury, he had put up a 1.47 ERA and a 3.24 FIP in 13 starts. During the rehab from his injury, his mechanics were thrown out of whack, and after he returned to the majors, he produced a 5.90 ERA and 5.76 FIP across nine starts. Ultimately, he was demoted to Triple-A in September to work on those mechanical inconsistencies.

Even if Senga is completely healthy in 2026, there were enough yellow flags in his first-half performance that a rebound back to the level of his excellent 2023 debut isn’t necessarily guaranteed. During those first 13 starts of the season, his strikeout-minus-walk rate was 13.3%, just a hair below league average and well short of the 18.0% K-BB% he posted during his first season in the US. Most of that was driven by a significant drop in strikeout rate.

You could point to his signature pitch, the ghost fork, as the reason why he wasn’t seeing as many swings and misses in 2025. And while that pitch was a little less effective last year, it was his cutter that saw the most dramatic drop in effectiveness. In 2023, his cutter was the fourth most valuable pitch in baseball by Run Value with a 2.9 RV/100, far outpacing his forkball (1.0 RV/100). In 2025, his cutter was exactly neutral with a 0.0 RV/100. Unlike his diving forkball, Senga’s cutter was a contact suppression machine during its peak, but batters made much higher quality contact against that pitch last year. That combination — a forkball that wasn’t getting as many swings and misses and a cutter that wasn’t generating as much weak contact — has me worried that Senga’s ceiling is far lower than we might think.

The projections are picking up on those concerns and see Senga taking a pretty significant step back in 2026. Health concerns aside, there are enough flags in his pitch arsenal that present enough risk to steer clear. And when you add his mechanical issues and injury history back into the picture, it’s a pretty easy call to avoid paying too high a price for Senga in 2026.

Keep or cut?

I’m cutting Senga in both of my leagues where I’m rostering him and I doubt I’ll be looking to redraft him in the spring.

Gavin Williams, SP
Salary: $11, $9, $8
Average Salary: $9
2025 P/G: 4.22
Projected 2026 P/G: 4.03

Through his first 11 starts of the year, Gavin Williams put up a rough 4.27 ERA and 4.65 FIP. It wasn’t terrible, but it was a concerning start to the season after an up-and-down year in 2024. From the beginning of June through the end of the season, his ERA fell by nearly two full runs down to 2.50 but his FIP only dropped to 4.27. His strikeout-to-walk ratio improved slightly during those final four months of the season but the biggest reason his ERA improved was thanks to a .221 BABIP and a 87.5% strand rate. Most of his underlying peripherals pointed to the same pitcher on the mound, but a ton of good batted ball luck helped him flip his season.

For Ottoneu players, an improved ERA shouldn’t necessarily help Williams’s fantasy production and a FIP above four is usually a bad sign. But here’s where understanding the ins and outs of your given format becomes extremely important.

In Ottoneu leagues using the FanGraphs points system — which critically takes hits allowed into account — Williams dramatically improved his production during the later half of the season. In leagues using the SABR points system — using only the inputs for FIP — Williams’s season was frustrating from start to finish.

As for Williams’s pitch arsenal, he was able to develop a very effective sweeper last year that returned a 44.0% whiff rate. That’s an excellent pitch to add to his repertoire, though his lack of command holds him back from really raising his ceiling. That’s sort of the big issue with his profile. He has a good, hard fastball, two excellent breaking balls, but he needed some incredible batted ball luck to turn into an effective pitcher for fantasy. His command was still an issue throughout the season, leading to some pretty inconsistent outings. Still, his Location+ improved from 91 during the first two months to 96 through the end of the year. That’s something to build off of, but until he’s able to make some significant improvements in that area, I fear his excellent stuff will be held back from reaching its maximum potential.

Keep or cut?

Thankfully, all three leagues where I’m rostering Williams use FanGraphs points, so I was able to partially enjoy his second half improvements in 2025. I’m probably keeping him at $8 and $9 but I think I’ll be cutting him at $11. His inconsistencies and command issues make him a risk to roster at a double-digit salary.

Yusei Kikuchi, SP
Salary: $5
Average Salary: $8
2025 P/G: 3.78
Projected 2026 P/G: 4.09

Coming off what seemed to be a mini-breakout during his short 10 start stint with the Astros during the second half of 2024, Yusei Kikuchi latched on with the Angels last year. Even though he was leaving the pitching development powerhouse in Houston, I expected the changes he implemented while he was there to stick in Los Angeles. Unfortunately, they didn’t. Some mechanical issues led to a drop in velocity and a lower arm slot affected the shapes of all his pitches. He spent most of the season working out the kinks in his delivery, slowly raising his arm slot and regaining some of his velocity.

I think the thing that worries me the most is the effectiveness of Kikuchi’s fastball. He’s one of the hardest throwing left-handers in baseball, but he’s entering his age-35 season in 2026. His velocity dropped early last year, and even though he regained it in the middle of the season, it dropped again in August and September and his results tanked along with it.

Last year, he generated the lowest whiff rate on his fastball since his debut season in 2019. Both his slider and changeup were a little less effective at getting swings and misses too. It all added up to a 5.5 point drop in strikeout rate and a much higher walk rate that was more in line with what he was posting during his time in Seattle.

Kikuchi has never been a model of consistency during his career. He’ll have dominant stretches from time to time, but his command issues have often held him back from reaching his ceiling. It looked like he had turned a corner in Toronto and Houston in 2023 and ‘24, but he came crashing back down last year thanks to his mechanical troubles. Steamer projects a small bounce back but he’s getting to the point in his career where the velocity of his fastball is sitting on a knife’s edge; dip just a little and the whole repertoire comes crashing down.

Keep or cut?

$5 is probably the highest I’d want to roster Kikuchi for heading into next season. There’s always the possibility he’ll figure out his mechanics over the offseason and post another strong season like he did in 2024, but there are too many flags to risk anything higher than that. I’ll probably keep him at $5, but he’s a quick cut if his fastball isn’t looking good in the spring.
