Seattle Mariners fans have another reason to celebrate as right-hander George Kirby etched his name into franchise history Monday night. The 27-year-old ace earned his 50th career win in Seattle's 3-1 victory over the Houston Astros at Daikin Park, joining an exclusive club of just 12 pitchers in Mariners history to reach that milestone.
Kirby was in control from the start, allowing just one run on seven hits while striking out seven and walking two. The performance improved his season record to 5-2 with a stellar 2.84 ERA, putting him on pace for the best season of his young career.
The win was especially sweet as it extended Seattle's dominance over their division rivals. The Mariners have now won all five meetings against Houston this season and eight straight dating back to last year, improving to 20-22 overall.
Kirby joins a distinguished list of Mariners legends who have reached 50 wins with the franchise, including Hall of Famers Randy Johnson, Ken Griffey Jr. (yes, he pitched too!), and Felix Hernandez. The complete list features names like Jamie Moyer, Mark Langston, Mike Moore, and Erik Hanson — pitchers who helped define Mariners baseball through the years.
Here's a fun fact for fans watching the rotation: teammate Logan Gilbert sits at 49 career wins, meaning he'll likely join this exclusive club in his next start. Gilbert is scheduled to take the mound Friday night against the San Diego Padres at T-Mobile Park.
Kirby, selected in the first round of the 2019 draft out of Elon University, made his MLB debut in 2022 and quickly established himself as one of baseball's premier control artists. He led the majors in strikeout-to-walk ratio in both 2023 and 2024, earning an All-Star nod in 2023. His career numbers now stand at 50-36 with a 3.52 ERA, and he's been a key contributor to Seattle's playoff runs in 2022 and 2025.
The Mariners continue their four-game series against the Astros on Tuesday at 5:10 p.m. PT, with Bryan Woo (2-2, 4.02 ERA) facing Tatsuya Imai (1-0, 7.27 ERA), who returns from the injured list. Seattle beat Imai earlier this season, so expect the M's to come out swinging.
Whether you're rocking your Kirby jersey or just love watching precision pitching, this is a milestone worth celebrating. The Mariners' rotation continues to prove why it's one of the most exciting in baseball — and George Kirby is leading the charge.
