Ryan Weiss made his Major League Baseball debut as a starting pitcher for the Houston Astros on April 17, 2026, facing the Colorado Rockies at Daikin Park in Houston, Texas. The 29-year-old, known as "Daejeon Jesus" during his time in Korea, had a mixed performance, ending the game with 3⅔ innings pitched, allowing 3 hits (including a home run), 4 walks, and recording 3 strikeouts and 2 earned runs.
Why it matters: Weiss's debut is a notable milestone in his career, marking his transition from KBO to MLB. This opportunity arose due to injuries within the Astros' starting rotation, highlighting the challenges players face when transitioning to the major leagues.
- Weiss, drafted in the 4th round of the 2018 MLB Draft by the Arizona Diamondbacks, had previously played in various leagues, including KBO and independent leagues.
- His performance was under scrutiny as he entered the game with a high ERA of 7.36 from prior relief appearances.
- The Astros' rotation has been affected by injuries, prompting Weiss's call-up as a starter.
Driving the news: Weiss's debut came at a time when the Astros were struggling with injuries, losing key pitchers like Hunter Brown and Cristian Javier to the injured list.
- He was initially slated to be a long reliever but was thrust into a starting role due to the team's shortage of available pitchers.
- In his debut, Weiss faced three consecutive batters in the third inning, issuing walks that led to a bases-loaded situation.
- He managed to limit the damage, allowing only one run during that inning, but faced difficulties maintaining control.
State of play: In the first inning, Weiss started strong, retiring the side in order and receiving run support from his teammates.
- After an impressive first inning, Weiss continued to pitch effectively until the third, where he encountered a sudden loss of command.
- He walked three consecutive batters, resulting in a precarious bases-loaded situation before allowing a run.
- In the fourth inning, Weiss surrendered a solo home run to Hunter Goodman, tying the game at 2-2 before being replaced.
The big picture: Weiss's transition from KBO to MLB has been closely watched, especially after his successful season with the Hanwha Eagles, where he recorded 16 wins and a 2.87 ERA.
- His performance in KBO earned him a contract with the Astros worth $2.6 million for one year, signaling high expectations.
- Weiss's ability to adapt to the pressures of MLB will be key in determining his future with the team.
- His debut reflects the increasing trend of international players making their mark in MLB, particularly from Asian leagues.
What they're saying: Weiss expressed mixed feelings about his performance following the game.
- “I felt good in the first inning, but I need to work on my command,” Weiss told reporters after the game.
- Astros manager Dusty Baker acknowledged the challenges Weiss faced but emphasized the importance of experience in the majors.
- “Every pitcher goes through this. It’s about how you respond next time,” Baker said.
By the numbers: Weiss's statistics from his debut highlight both his struggles and potential.
- He threw a total of 76 pitches during his outing, with a mix of fastballs and sliders.
- His ERA improved slightly from 7.36 to 6.75 following the game.
- In his previous five appearances, Weiss had not recorded a win, which added pressure to his first start.
Between the lines: Weiss’s path to MLB was not straightforward, experiencing setbacks along the way.
- After being drafted, he spent years in the minors and independent leagues before finding success in Korea.
- His transition back to the U.S. and into the MLB spotlight showcases the unpredictability of a professional sports career.

What's next: Following his debut, Weiss is expected to continue to be a part of the Astros' rotation as they navigate injuries.
- He will likely have opportunities for more starts as the team assesses its pitching depth.
- His next outing will be closely monitored as he looks to build on his experience and improve his performance.
- With the Astros in a competitive division, every game is important, and Weiss's contribution could be key to their success moving forward.
