Astros Sign Ryan Weiss To Major League Deal
December 11th: Chandler Rome of The Athletic reports that Weiss’s club option for 2027 is worth $5M with a $500K buyout.
December 9th: The Astros have now officially announced their signing of Weiss. The opened two roster spots last week by outrighting Taylor Trammell and Logan VanWey. Their 40-man count is now at 39.
December 2nd: The Astros have reportedly agreed to a major league deal with right-hander Ryan Weiss, who has been pitching in Korea lately. Weiss is guaranteed $2.6MM and there’s a club option for 2027. The Sports One Athlete Management client could potentially earn $10MM over the course of the pact. The Astros have a full 40-man roster and will need to make a corresponding move to make this official.
It’s a bit of an early birthday present for Weiss, who turns 29 next Wednesday. A fourth-round draft pick of the Diamondbacks back in 2018, he showed enough promise as a minor leaguer that the Snakes added him to their 40-man in November of 2021 to keep him out of the Rule 5 draft. He had just tossed 78 1/3 minor league innings in that 2021 season with a 4.60 earned run average and 9.5% walk rate but his 27% strikeout rate was quite good.
He struggled in the minors in 2022 and was placed on waivers, with the Royals placing a claim. Kansas City then passed him through waivers unclaimed in October of 2022. The Royals then released him in May of 2023. At that point, Weiss had tossed 76 1/3 innings on the farm, dating back to the start of 2022. In that time, he allowed 6.96 earned runs per nine.
That release kicked off a nomadic period for Weiss. He then landed with the High Point Rockers of the independent Atlantic League. After a few months there, with a 4.61 ERA, he signed with the Fubon Guardians of Taiwan’s Chinese Professional Baseball League. He had a decent 2.32 ERA there, though in just 31 innings. He started 2024 back with the Rockers, posting a 4.61 ERA over nine starts.
In June of 2024, he signed with the Hanwha Eagles of the Korea Baseball Organization. It was with that club that he seemed to unlock a new gear. In 2024, he gave the Eagles 16 starts with a 3.73 ERA, 25.5% strikeout rate, 7.6% walk rate and 48.2% ground ball rate. He returned to the Eagles in 2025 and took the ball 30 more times. He logged 178 2/3 innings with a 2.87 ERA, 28.6% strikeout rate, 7.7% walk rate and 48.5% ground ball rate.
Weiss then pitched in relief for the Eagles in the playoffs but the Astros plan to utilize him as a starter. Houston has plenty of uncertainty in their rotation mix. They just lost Framber Valdez to free agency. Luis Garcia required another Tommy John surgery late in 2025 and has been jettisoned from the roster. Hayden Wesneski, Ronel Blanco and Brandon Walter also had TJS in 2025 and are slated to begin next year on the injured list.
That left the Astros going into 2026 with Hunter Brown and a heap of question marks behind him. Cristian Javier will be in the mix but he had a 4.62 ERA in 2025 after returning from his own lengthy surgery layoff. Lance McCullers Jr. has had all kind of injury troubles and put up a 6.51 ERA this year. Spencer Arrighetti was good in 2024 but spent most of 2025 on the IL and only made seven starts. Jason Alexander had some passable results this year but he’s a journeyman depth guy who’s about to turn 33. J.P. France spent most of 2025 recovering from shoulder surgery. Colton Gordon and AJ Blubaugh are on the 40-man but lacking in experience.
Upgrading the rotation for 2026 makes plenty of sense but it appears the club doesn’t have a ton of spending capacity. Reportedly, owner Jim Crane would prefer to avoid the competitive balance tax in 2026. RosterResource projects them for a $218MM CBT number next year. That’s more than $20MM below next year’s $244MM base threshold but the club also has other needs to address this winter. Trading someone like Christian Walker or Jake Meyers might free up some extra space but it’s somewhat tight for now.
So far, their rotation additions have been of the low-cost wild card variety. They took a flier on former top prospect Nate Pearson, signing him to a $1.35MM guarantee. Now they’ve added Weiss into the mix as well. Perhaps there’s a more surefire rotation upgrade over the horizon. For now, the Astros are making a modest bet that Weiss transfer some of his strong KBO results to the MLB level. For his part, Weiss gets a nice paycheck despite still having no major league experience.
Reporter Daniel Kim first reported that the two sides were close to a deal. Brian McTaggart of MLB.com reported that an agreement was in place for a major league pact and that Weiss will be a starter. Jesse Rogers of ESPN reported the guarantee, the presence of a ’27 option and the possibility for the deal to go beyond $10MM. Chandler Rome of The Athletic specified that the option is a club option.
Diamondbacks Claim Tyler Zuber From Royals
The Royals announced that right-hander Tyler Zuber has been claimed off waivers by the Diamondbacks. Zuber has been on the 60-day injured list all season and won’t require a 40-man roster spot for the time being. Additionally, the Royals also announced that right-hander Ryan Weiss has cleared waivers and been outrighted to Triple-A Omaha.
Zuber, 28 in June, missed the entirety of the 2022 due to a shoulder impingement, though he was recently able to resume throwing. He appeared in the majors in 2020 and 2021, though without much success. In 49 1/3 career innings, he has a 5.29 ERA, with a strong 24.8% strikeout rate but a ghastly 16.7% walk rate.
He still has one option year remaining and has yet to reach arbitration eligibility, but the Royals are evidently doing some roster cleanup at the moment. Most teams have roster crunches upcoming since there’s no injured list between the World Series and Spring Training. That means players on the 60-day IL, who don’t count against a club’s 40-man count, will soon be returning to their respective rosters. In anticipation of that, the Royals have cut Zuber, Weiss and Luke Weaver from their roster, with Weaver having been lost to the Mariners on a separate waiver claim.
For the D-Backs, they don’t need a roster spot for Zuber just yet but will soon. They are likely looking past his major league results and focusing on his work in the minors thus far. Last year, Zuber threw 28 2/3 Triple-A innings with a 2.83 ERA while striking out 37.1% of batters faced. The control problems were still there, however, as Zuber walked 13.8% of those who stepped to the plate. If he can hang onto his 40-man roster spot through the winter, he could serve as optionable depth for Arizona in 2023 while they try to iron out that command.
As for Weiss, 26 in December, he’s yet to make his MLB debut. He was drafted by the Diamondbacks and was added to their 40-man roster in November of last year, eventually going to the Royals on a midseason waiver claim. Between the two organizations, he registered a 6.93 ERA over 62 1/3 innings in 2022. This is his first career outright and he doesn’t have the three years of MLB service time or seven years of minor league experience necessary to have the right to reject it. He’ll stick with the Royals as depth but without occupying a 40-man roster spot.
Royals Claim Ryan Weiss, Designate Matt Peacock For Assignment
The Royals have claimed right-hander Ryan Weiss off waivers from the D-backs and optioned him to Triple-A Omaha, per a club announcement. Right-hander Matt Peacock was designated for assignment to open a spot on the 40-man roster. Meanwhile, fellow righty Wyatt Mills, whom the Royals acquired from the Mariners in this week’s Carlos Santana trade, has been recalled from Omaha to take Peacock’s spot on the big league roster. He’ll be making his team debut when he gets into a game.
Weiss, 24, was Arizona’s fourth-round pick back in 2018 and ranked 18th among D-backs farmhands a year later in 2019. At the time, BA praised his prototypical starter’s frame, athleticism, delivery and a repertoire fronted by three above-average pitches. However, Weiss has posted lackluster results in Double-A and pitched poorly in a hitter-friendly Triple-A setting since that time, and the Snakes have moved him to a bullpen role this season. In 26 2/3 frames on the year, he’s logged an unsightly 5.74 ERA (which includes eight runs in 9 2/3 innings at the Triple-A level).
The 28-year-old Peacock has split the 2022 season between these same two teams — D-backs and Royals — pitching to a combined 5.40 ERA in 10 innings. He made his big league debut with Arizona last season but struggled to the tune of a 4.90 ERA over the life of 86 1/3 innings. Peacock owns a career 3.02 ERA in Double-A but has just 18 rocky Triple-A innings and 96 1/3 similarly tough MLB frames under his belt so far. The Royals will have a week to trade him, pass him through outright waivers or release him.
Diamondbacks Designate Ryan Weiss For Assignment
The Diamondbacks announced a few roster moves prior to today’s game. As was previously reported, lefty Dallas Keuchel was selected to the roster to start today’s game. To create room on the active roster, right-hander Sean Poppen was optioned following yesterday’s game. To create space on the 40-man roster, righty Ryan Weiss was designated for assignment.
A fourth round selection in the 2018 draft, Weiss was primarily a starter in his first few years as a pro. Based on a solid showing at some stops in the lower levels of the minors, he was ranked the #18 prospect in the system by Baseball America in 2019. As Weiss has climbed the ladder, however, he’s been gradually transitioned into bullpen duty. Last year, between Double-A and Triple-A, he threw 78 1/3 innings with a 4.60 ERA, 27% strikeout rate and 9.5% walk rate.
That was enough for Weiss to get added to the club’s 40-man roster in November, ahead of the Rule 5 draft that ended up getting quashed by the lockout. This year, however, things have gone south for Weiss, as he’s put up a 5.74 ERA in 26 2/3 innings, again split between Double-A and Triple-A. He’s improved his walk rate to 6.7% but also seen his strikeout rate dip to 20.8%.
Based on those mediocre results this season, it’s easy to see why the Diamondbacks felt they had to move on. However, he may still have appeal to other clubs based on the fact that he’s still just 25 years old and has all three of his option years remaining.
