Seattle Mariners extend pitcher Luis Castillo to five-year, $108 million contract

On Saturday, September 24 the Seattle Mariners extended right-handed pitcher Luis Castillo to a five-year, $108 million contract. The contract is worth $108 million and could reach $133 million through a sixth-year vesting option according to ESPN Jeff Passan.

Passan noted that the deal also included “If from 2025-27 he undergoes UCL repair surgery on his right elbow that keeps him out for 130+ days, the Mariners will receive a $5 million option on the 2028 season, sources tell ESPN. Seen as downside protection against future injury.” This is the worst-case scenario though and Castillo’s extension should be looked at with the utmost optimism.

Since arriving in Seattle, Castillo has been dominant for the Mariners with over 68 strikeouts, a 2.83 ERA, and a 3-2 record as of September 24th.

The Mariners acquired Castillo from the Cincinnati Reds near the end of the trade deadline in late July. In return, Cincinnati received SS Noelvi Marte, SS Edwin Arroyo, RHP Levi Stoudt, and RHP Andrew Moore. In his home debut in Seattle, in eight scoreless innings giving up three hits, two walks, and seven strikeouts. The Mariners ended up winning the game 1-0 on a walk-off hit by Luis Torrens in the bottom of the 13th.

The Mariners now have former 2021 American League Cy Young winner Robbie Ray and Castillo locked in for at least four years. Not to mention their other young talent on their pitching staff including Logan Gilbert and George Kirby. The future looks bright for the Mariners and it was a good move by them to extend Castillo.
