Overview

  • Castillo has logged 21 2/3 innings this season between Arizona and New York with a 4.98 ERA, 22 strikeouts and nine walks across 21 relief appearances.
  • He has been designated for assignment multiple times in 2025, first by the Diamondbacks in May and three times by the Mets.
  • The move gives Seattle another left-handed bullpen option alongside Gabe Speier, Caleb Ferguson and Tayler Saucedo.
  • With between four and five years of service time, Castillo could be retained for 2026 via arbitration if he remains on the roster through season’s end.
  • Jacques, 30, was acquired from the Dodgers on June 2 for Will Klein and has a 6.51 ERA with 53 strikeouts in 47 Triple-A innings this season.
