Ryan Weiss

29-Year-Old PitcherRP
Houston Astros AAA
2026 Fantasy Outlook
Weiss is part of a large group of pitchers returning from overseas this winter, though unlike the rest of them, he's yet to make his big-league debut. He signed with the CPBL's Fubon Guardians two years ago as a 27-year-old after struggling to a 6.72 ERA and 1.80 WHIP across parts of three seasons at the Triple-A level, then moved on to the KBO's Hanwha Eagles five starts later. Weiss took big steps forward in his two seasons in Korea, particularly this past year, where he helped his team reach the Korean Series by posting a 2.87 ERA and 1.02 WHIP across 30 starts, pairing a 28.6 K% with a 7.7 BB%. It was enough to convince the Astros to sign him to a one-year, $2.6 million deal, though that's not a contract which implies the team is committed to giving him a rotation role. He appears lined up to compete for a back-end starter job this spring, but he may fit best in the bullpen, where his fastball and slider could cause problems for righties if his stuff ticks up in shorter stints.

PHouston Astros  AAA
May 5, 2026
The Astros optioned Weiss to Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.
Analysis
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.
