The Astros optioned Weiss to Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.
Weiss was lit up for seven runs (six earned) over 4.1 innings during Monday's loss to the Dodgers, inflating his ERA to 7.62 to go with a 2.12 WHIP through 26 innings on the year. He'll now head back to the minors to try to right the ship, and Jason Alexander will come up from Triple-A to round out Houston's bullpen.

Astros' Ryan Weiss: Surrenders sevens runs in loss
Rotowire
Weiss (0-3) took the loss in Monday's 8-3 loss to the Dodgers. He allowed seven runs (six earned) on eight hits and four walks while striking out five over 4.1 innings.
Entering after opener Steven Okert recorded two outs, Weiss struggled in bulk relief as the Dodgers lineup did significant damage. The 29-year-old has yet to find his footing in 2026, allowing runs in seven of his nine appearances this season. With a 7.62 ERA and 2.12 WHIP across 26 innings, Weiss will likely continue to operate in a long-relief role and will need to turn things around quickly to keep his spot on the roster secure.

Astros' Ryan Weiss: Back from paternity list
Rotowire
The Astros reinstated Weiss (personal) from the paternity list Sunday.
The right-hander was away from the team for the last three days while welcoming a new addition to his family. The Astros haven't clarified what Weiss's role will look like, but he could be available out of the bullpen to cover multiple innings behind Cody Bolton, who will open Sunday's contest. If Weiss isn't used Sunday, he'll be a candidate to start or work in bulk relief during Monday's series opener versus the Dodgers.

Astros' Ryan Weiss: Inefficient in no-decision
Rotowire
Weiss didn't factor into the decision in Tuesday's 8-5 loss to the Guardians, giving up two runs on five hits and four walks over 3.1 innings. He struck out four.
The 29-year-old right-hander needed 86 pitches (48 strikes) to record just 10 outs, as Weiss continues to struggle in his return to MLB. Weiss has yet to complete four innings in any of his seven appearances (two starts), stumbling to a 6.50 ERA, 2.17 WHIP and 22:14 K:BB over 18 innings, and with Houston having a couple off days coming Thursday and Monday, Weiss could have his next turn in the rotation skipped. Whether he gets another start or returns to a long-relief role will depend on when the likes of Tatsuya Imai (arm) or Cody Bolton (back) are cleared to come off the IL.

Astros' Colton Gordon: Shifts to bullpen
Rotowire
Gordon struck out five and allowed three earned runs on four hits and one walk across 2.2 innings out of the bullpen in Saturday's 7-5 loss to the Cardinals.
Earlier in the week, Houston recalled Gordon from Triple-A Sugar Land and plugged him into a rotation that had recently lost all of Hunter Brown (shoulder), Cristian Javier (shoulder), Tatsuya Imai (arm) and Cody Bolton (back) to the injured list. Gordon was lit up for four earned runs on eight hits across 3.2 innings while taking a no-decision Tuesday in Houston's 7-6 win over Colorado, and the poor showing as a starter followed by the extended relief appearance looks like it will at least temporarily keep the left-hander from receiving additional turns through the rotation. Ryan Weiss and Peter Lambert would now appear to be the likely candidates to fill out the final two spots in the Houston rotation, which could be scaled back from six men to five during the upcoming week with an off day looming Thursday.

Astros' Ryan Weiss: Inefficient in first MLB start
Rotowire
Weiss didn't factor into the decision Thursday against the Rockies, allowing two runs on three hits and four walks while fanning three across 3.2 innings.
The right-hander made his first start of his MLB career Thursday, but as had been the case in his previous two relief appearances, he didn't have much success. Weiss has tossed between 2.1 and 3.2 innings in four outings since the beginning of April, stumbling to a 7.71 ERA, 2.23 WHIP and 13:8 K:BB in 11.2 innings. Despite all the injuries to the Houston rotation, Weiss could be headed back to a long-relief role after this performance.

Astros' Ryan Weiss: Working out of bullpen
Rotowire
Weiss delivered two hitless innings in relief in Monday's win over the Red Sox, striking out three while walking one.
Weiss failed to crack Houston's rotation out of spring training, though he did make the team as a bullpen option. The right-hander looked sharp Monday, as he set down six straight Red Sox after issuing a leadoff walk in the eighth. It was an encouraging performance for Weiss, after he gave up a home run to Zach Neto in his major league debut Friday. While Weiss could work his way into the high-leverage picture, he's more likely to serve as a swingman or long-relief option this year.

Astros' Ryan Weiss: Competing for final rotation spot
Rotowire
Weiss delivered 2.1 scoreless innings in Thursday's Grapefruit League matchup with the Mets, allowing a hit and a pair of walks.
It was a solid spring debut overall for Weiss, as he was able to work out of trouble to keep the Mets off the board. The 29-year-old right-hander is competing with Spencer Arrighetti, Lance McCullers and AJ Blubaugh for one of the final two spots in the Astros' six-man rotation. Weiss, who featured a mid-90's fastball paired with three different offspeed pitches, signed a one-year deal with Houston after posting an impressive 2.87 ERA with 207 strikeouts across 178.2 innings in the KBO last year. Weiss figures to start the year as a swingman out of the bullpen, should he fail to crack the Opening Day rotation.

Astros' Ryan Weiss: Inks deal with Astros
Rotowire
The Astros signed Weiss to a one-year contract Tuesday, Brian McTaggart of MLB.com reports.
Weiss is getting a major-league contract after spending part of 2023 in independent ball and the last two seasons with the Hanwha Eagles of the Korea Baseball Organization. The right-hander had an excellent 2025 campaign with the Eagles, posting a 2.87 ERA and 207:56 K:BB over 178.2 innings covering 30 starts. Weiss -- who turns 29 next week -- will be used as a starting pitcher by the Astros. He has not appeared in a major-league game.

Diamondbacks' Ryan Weiss: Loses spot on 40-man roster
Rotowire
Weiss was designated for assignment by the Diamondbacks on Sunday.
Weiss was added to the 40-man roster in November but failed to make the Opening Day roster, and he's been removed from the 40-man roster without seeing the majors. The 25-year-old has a 7.45 ERA, 2.28 WHIP and 10:7 K:BB in seven appearances for Triple-A Reno this year.
