Dodgers Restructure Bullpen with Feyereisen and Loutos Additions

Los Angeles shifts Kopech and Treinen to 60-day IL to make room for veteran reliever J. P. Feyereisen and rookie Ryan Loutos.

Overview

  • The Los Angeles Dodgers claimed right-handed pitcher J. P. Feyereisen off waivers from the Arizona Diamondbacks and acquired rookie reliever Ryan Loutos from the St. Louis Cardinals for cash considerations.
  • Michael Kopech and Blake Treinen were transferred to the 60-day injured list to free up roster space for the new acquisitions.
  • Feyereisen, who has a 3.07 ERA across five MLB seasons, made two appearances for the Diamondbacks in 2025 before being designated for assignment.
  • Loutos, 26, debuted in the majors in 2024 and has yet to allow a run in his three MLB appearances; he has also shown promise in Triple-A this season.
  • The moves highlight the Dodgers' efforts to address bullpen challenges through a mix of experienced and emerging talent.
