Mets Designate Adrian Houser, Shintaro Fujinami For Assignment

The Mets announced a series of roster moves Friday, designating righties Adrian Houser and Shintaro Fujinami for assignment in order to open roster space for the return of Kodai Senga and the recall of righty Eric Orze from Triple-A Syracuse. (Fujinami was technically reinstated from the injured list prior to his DFA.) The Mets also placed righty Dedniel Núñez on the 15-day injured list due to a right pronator strain.

Houser, now 31, was acquired from the Brewers in the offseason alongside outfielder Tyrone Taylor. David Stearns had just been installed as the Mets’ new president of baseball operations and was familiar with both players from his time in Milwaukee.

The righty was coming off five fairly solid seasons with the Brewers, primarily as a starter. From 2019 to 2023, Houser had made 120 appearances for Milwaukee with 97 of those being starts. In his 523 2/3 innings, he allowed 4.04 earned runs per nine. His 19.2% strikeout rate was subpar but his 9.1% walk rate was close to average and he kept the ball on the ground at a strong clip of 52.5%.

It was hoped that he could serve a similar back-end role in the rotation in Queens but that didn’t go according to plan. Houser made six starts through early May but had an 8.16 ERA in those and got bumped to the bullpen. Since losing his rotation spot, his results have looked similar to his old self. In his last 40 2/3 innings, he has a 4.20 ERA, 16.9% strikeout rate, 7% walk rate and 50.8% ground ball rate.

Despite his results evening out, he has been squeezed off the Mets’ roster, perhaps not coincidentally just before the trade deadline. The Mets started the season with Senga and David Peterson on the injured list but both are now back on the roster. Though Christian Scott is now on the IL with a sprain of his UCL, the rotation mix now includes Senga, Peterson, Sean Manaea, Luis Severino, Jose Quintana and Tylor Megill with José Buttó in the big league bullpen.

Houser was largely blocked from getting another rotation gig there but perhaps he could be of interest to another club in need of starting pitching. Houser won’t be as exciting as aces like Garrett Crochet or Tarik Skubal but there are clubs who arguably just need solid back-end innings, such as the Guardians, Astros, Padres, Atlanta or Houser’s former club in Milwaukee. He is making $5.05MM this year, with roughly $1.7MM still to be paid out. He’s on pace for free agency at season’s end.

Fujinami, 30, put up huge strikeout numbers in Japan but also with worrying control problems. Those trends continued last year, his first in North America, split between the Athletics and Orioles. In 79 innings, he struck out 23.2% of batters faced but also gave out walks at a 13.2% clip. His 7.18 ERA last year was gruesome but likely not indicative of his true talents as he only stranded 53.4% of runners, with his 4.61 FIP and 4.60 SIERA finishing in nicer shape.

The Mets took a shot on him by signing him to a one-year, $3.35MM deal in the offseason but he hasn’t yet pitched for them. He began the year on optional assignment, getting recalled in mid-May to be placed on the injured list with a shoulder strain. He began a rehab assignment a couple of weeks ago but the Mets evidently didn’t want to make room for him on their roster.

The results prior to hitting the IL were very bad, as Fujinami had a 14.09 ERA in 7 2/3 innings. Since starting his rehabbing assignment, things have been better, with a 3.12 ERA in 8 2/3 innings, but evidently not impressive enough for the Mets to want to hang on to him.

The club will now have until the trade deadline to explore trades of either player. Houser could perhaps entice clubs based on his track record while Fujinami has some theoretical upside via his potent but wild arsenal. If the Mets can unload either player, they would likely save more money than any other club would take on. As a third-time competitive balance tax payor, they are paying a 110% tax on all spending over the top tier. Though Fujinami is only owed about $1.16MM at this point, the Mets could save more than double that amount when factoring in the taxes.
