We’ll explore the significance of this accomplishment, the context of the Mariners’ season, and the esteemed company Castillo now keeps among franchise greats.
Navigating an Injury-Riddled Season
The 2025 season presented numerous hurdles for the Seattle Mariners, particularly within their starting rotation. Key pitchers, including Logan Gilbert, George Kirby, and Bryce Miller, each spent considerable time on the injured list, disrupting the team’s rhythm and placing added pressure on the remaining starters.
Logan Gilbert and George Kirby have been working diligently to regain their midseason form following their respective ailments. Meanwhile, Bryce Miller is on the cusp of a return, scheduled for his third rehab start with the Triple-A Tacoma Rainiers on Wednesday. Miller’s journey back to the majors has been delayed by right elbow inflammation, marking his second stint on the IL.
Amidst this instability, Luis Castillo and Bryan Woo stood firm, providing much-needed consistency to the Mariners’ pitching staff. Castillo has made 24 starts, showcasing his durability and reliability. Woo has been impressive in his 23 starts.
Castillo’s Historic Achievement
Luis Castillo has surpassed 500 innings pitched with the Seattle Mariners, marking a significant milestone in his career with the franchise. Surpassing this threshold places him in elite company in the Mariners’ record books. According to Mariners PR, Castillo now leads the franchise in ERA among all pitchers who have thrown at least 500 innings for the team.
Castillo’s ERA of 3.38 tops a list that includes some of the most iconic pitchers in Mariners’ history. Among those he leads are Hall of Famer Randy Johnson (3.42), Mariners Hall of Famer Felix Hernandez (3.42), Hisashi Iwakuma (3.42), and James Paxton (3.42). Castillo also currently holds a lead over his current teammates George Kirby (3.51) and Logan Gilbert (3.58).

Comparison to Mariners Legends
To fully appreciate the magnitude of Castillo’s accomplishment, it’s essential to compare his numbers to those of other Mariners legends. Randy Johnson, a Hall of Famer, spent a decade in Seattle, dominating hitters with his fastball and slider. Felix Hernandez, known as ‘King Felix,’ was a Mariner for 15 seasons, earning numerous accolades and a Cy Young Award.
Johnson and Hernandez set high standards for pitching excellence in Seattle, making Castillo’s achievement all the more impressive. While Johnson was known for his overpowering stuff and Hernandez for his longevity and artistry, Castillo has carved his own path. His ability to combine velocity, movement, and command has made him one of the most effective pitchers in the American League.
Castillo’s ERA of 3.38 is a testament to his consistency and effectiveness. To maintain such a low ERA over 500 innings requires a combination of skill, durability, and mental fortitude.
