"Logan Gilbert, George Kirby and have all made an All-Star team in the past couple years. All three have a career ERA of 3.61 or better with better-than-average strikeout and walk rates alike. Bryce Miller hasn't had as much success relative to his teammates, but he posted a 3.52 ERA with quality strikeout and walk rates in his first 56 MLB starts before an injury-ruined 2025 season (90 1/3 innings, 5.68 ERA, two IL stints for elbow inflammation)."
"Veteran righty Luis Castillo wasn't signed and developed by the Mariners, but Seattle pried him from Cincinnati in a 2022 trade for a package headlined by infield prospects Noelvi Marte and Edwin Arroyo. The M's quickly extended Castillo on a five-year, $108MM deal. In parts of five seasons with Seattle, his 3.61 ERA is right in line with the previously mentioned group (and a near-identical match to his 3.62 mark in six seasons with the Reds)."
"No organization in baseball has had more continuity in its major league rotation than the Mariners since this wave of pitchers arrived on the scene at T-Mobile Park. They've been consistent, productive and, with the exception of Miller's recent injury issues, largely durable. That's been key for the Mariners, because one less-talked-about aspect of their strong rotation is that the depth behind the group hasn't been great."
"From 2022-25, the quintet of Gilbert, Kirby, Woo, Miller and Castillo started 75% of the Mariners' games. (Castillo wasn't even acquired until July 29 of the 2022 season.) The Mariners had rotation cameos from (signed to a five-year deal, missed the second season due to Tommy John surgery, then traded to the Giants), Chris Flexen (26 starts on the back end of his low-cost contract) and Marco Gonzales (a holdover from the prior rotation group who was eventually traded while injured). But for the most part, it's been the same group of five, which has helped to ma"
Logan Gilbert, George Kirby, and other Mariners starters have produced strong results with career ERAs of 3.61 or better and strikeout and walk rates above average. Bryce Miller has been less successful than teammates, posting a 3.52 ERA with quality strikeout and walk rates in his first 56 MLB starts before an injury-ruined 2025 season. Luis Castillo, acquired from Cincinnati in 2022 and extended to a five-year, $108MM deal, has matched the group’s performance with a 3.61 ERA in Seattle. Since these pitchers arrived at T-Mobile Park, the rotation has shown notable continuity, consistency, productivity, and durability, which has mattered because rotation depth has been limited. From 2022-25, the core group started 75% of games, with only occasional contributions from other pitchers.
