Ryan Weiss

29-Year-Old PitcherRP
Houston Astros
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.

ADP
Signed a one-year, $2.6 million contract with the Astros in December of 2025. Contract includes $5 million team option ($500,000 buyout) for 2027.
Starting Thursday
PHouston Astros
April 15, 2026
Weiss is slated to start Thursday's game against the Rockies in Houston, Brian McTaggart of MLB.com reports.
Analysis
Weiss has been hit around quite a bit during his last two relief appearances, conceding nine runs (eight earned) on 12 hits and four walks while striking out eight batters over five innings. However, the Astros are running low on options with seven starting pitchers currently on the injured list, so the 29-year-old righty will be called upon to make his first MLB start. He'll at least benefit from a favorable matchup, as the Rockies rank in the bottom third of MLB with a .681 OPS.
