2026 Fantasy Outlook
Houser had a tale of two seasons in 2025 between the White Sox and Rays. He was one of the bright spots in the White Sox rotation, making 11 starts while winning six of them pitching to a 2.10 ERA and 1.22 WHIP despite a 9.1 K-BB percentage. The White Sox smartly sold high to Tampa Bay for Curtis Mead, and while Houser's K-BB percentage improved to 11.9, regression caught up with him as his ERA ballooned to 4.79 and his WHIP to 1.35 in 10 starts with Tampa Bay. Nine of his 11 starts with Chicago were quality starts, while just two of his 10 with Tampa Bay qualified as such. The Rays were making some adjustments to Houser after the deal and helped him tap into some more velocity, but none of that should elevate Houser out of mixed league streamer or endgame AL-Only status. He is still a pitcher with a risky career 9.4 K-BB percentage with a 4.06 ERA and 1.36 WHIP who is a prototypical fifth starter on a second division major league club. Draft accordingly.

Logs quality start in loss
PSan Francisco Giants
May 6, 2026
Houser (0-4) took the loss Wednesday against San Diego, allowing two runs (one earned) on three hits and a walk over six innings. He struck out three.
Analysis
While Houser remains winless on the season, Wednesday's outing was easily his best so far this year, as he turned in his first quality start and held the Padres to a lone earned run on a Gavin Sheets fourth-inning homer. In six starts prior to Wednesday, Houser hadn't allowed fewer than three runs while making it through six innings just once. His ERA now sits at 6.19 with a 1.54 WHIP and 19:11 K:BB across 36.1 innings. Houser is currently in line to face the Dodgers on the road his next time out.

Past Fantasy Outlooks

2022
2021
2020
2017
2016
Houser's time in Milwaukee has come to an end as the club traded him to the Mets in December. The right-hander reached his apex in the Brewers organization in 2021 when he went 10-6 with a 3.22 ERA and 1.28 WHIP over 142.1 innings. He has been unable to replicate the results or the workload in the years since, though 2023 was mostly a positive season around stints on the injured list due to groin and elbow issues. Houser took the ball 23 times (21 starts) and cut his walk rate down to the lowest mark of his career. He might be a good fit in spacious Citi Field given his heavy sinker-slider approach. The modest strikeout rate leaves him on the fringes in most fantasy leagues, but Houser should be in the Opening Day rotation for the Mets in 2024.
Houser remained a fixture in the Brewers' rotation in 2022, finishing top-4 among Brewers pitchers in starts for a third straight year. However, he missed nearly two months with an elbow injury and was not particularly effective when he was out there, as both his ERA and WHIP were notably higher than they were in 2021. Houser took most of his lumps against left-handed hitters and on the road, as his splits against righties and at home were palatable or better. The Brewers have five other pitchers capable of breaking camp in the rotation, so despite his reliability Houser will not be guaranteed a spot, especially after the offseason signing of Wade Miley. Even if he comes away with one, it might be tough to believe in a bounceback, as although his velocity has remained steady, he will be entering his age-30 season and both his K/9 and BB/9 have trended the wrong direction three years running.
Houser had his best season to date with a career high in innings pitched and a career-low 3.22 ERA. It's a little surprising he excelled. While he was able to maintain a groundball rate close to 60% (59.0 GB% last season), his K-BB% declined for the second straight season (17.3% to 9.3% to 6.8%). His K-BB% was fourth lowest among the 68 pitchers who threw at least 140 innings. Most of his struggles came after Major League Baseball started enforcing the ban on foreign substances; his curveball averaged over 1900 rpm in April and was down around 1750 in July. Houser only posted a 5.5 K/9 in the second with no late signs of a rebound. His success is predicated on the defense behind him getting to the groundballs he generates.
A strong finish to end the 2019 season earned Houser a spot in the Brewers' rotation last season, and he picked up where he left off, giving up just one run over his first two outings. However, things went south from there, as he failed to make it past the five-inning mark in eight of his final nine starts and posted a 6.70 ERA over that span. After averaging over a strikeout per inning in the previous campaign, Houser averaged just 7.1 K/9 last year, and he also had trouble keeping runners off the bases and the ball in the park. The Brewers did not address their rotation over the offseason, so Houser is a good bet to break camp with a starting spot. To hang onto it, he will need to find more zip on his fastball and slider after both dropped off a year ago.
Houser spent all but one day in the minors during the first month of last season, but he was recalled for good in early May, and was surprisingly one of the Brewers' best pitchers during the 2019 campaign, both in relief and as a starter. After two impressive months out of the bullpen Houser joined the rotation in late June. He took some lumps early, but he was stellar over his last 10 starts, posting a 3.02 ERA, 1.03 WHIP and 9.8 K/9 -- numbers that put him in prime position to open next season somewhere in the middle of the Brewers' rotation. Houser brings a mid-90s fastball and a quality curveball to the table, and he kept hitters off balance last season by mixing in a slider and changeup. Houser was once the least-heralded prospect in the deal that sent Josh Hader to the Brewers and Carlos Gomez to the Astros, but if he can repeat his late-season surge, he could really make a name for himself in 2020.
Houser was just one of the many former Astros plucked away to Milwaukee by new(ish) Brewers general manager David Stearns, who worked under Jeff Luhnow in Houston's front office. Despite a 5.25 ERA, Houser had solid peripherals in his first 13 starts of 2016 down at Double-A, thanks to an acceptable 56:22 K:BB over 70.1 innings. Unfortunately his season was ended by Tommy John surgery in July, which will keep him out for most, if not all of 2017. He turns 24 in February, so Houser will have time to get his career back on track. However, this is a very untimely development for Houser, whose performance in the 2015 Arizona Fall League had many believing he could be a part of the Brewers future plans sooner rather than later. His likely future role is a back-of-the-rotation arm or middle reliever, so given the elbow surgery, he can be ignored in almost all dynasty leagues.
The Brewers received Houser as part of the deal that sent Carlos Gomez to the Astros at the trade deadline in July. Houser struggled at Double-A in the Astros system, as hitters tagged him for six home runs in five starts. Things cleared up for him after the trade, as Houser struck out 32 batters in 37 innings for the Brewers and went on to pitch a solid 25.1 innings (3.51 ERA, 19 strikeouts) in the Arizona Fall League. He has a big fastball that reaches into the upper-90s and that gives the Brewers reason to dream on his upside, but he has yet to show the control or command of a secondary pitch that he'll need to succeed as a starter. He'll likely begin 2016 with another tour of Double-A.

Latest Fantasy Rumors
Likely to be dealt
PChicago White Sox
July 25, 2025
Houser is likely to be traded by the White Sox ahead of the July 31 deadline, reports Ken Rosenthal of The Athletic.
Analysis
The veteran right-hander had a 5.03 ERA in nine outings at Triple-A with Texas before hitting free agency in mid-May, so his 1.89 ERA in 10 starts since signing with Chicago has been a major surprise. Some regression is likely on the horizon given his 6.4 K/9 and 3.01 FIP, but Houser should still be an easy asset to move at the deadline given his cheap expiring contract.
