In another move to bolster their relief corps, the Dodgers claimed right-handed reliever J.P. Feyereisen off waivers from the Arizona Diamondbacks.

Loutos, 26, made three appearances for the Cardinals last season without allowing a run. He began this season at Triple-A Memphis, where he's allowed three runs in eight innings (3.38 ERA) across eight relief appearances.
An undrafted free agent signee out of Washington University in St. Louis, Loutos has spent his entire professional career (2021-24) in the Cardinals organization.

Perhaps uniquely, Loutos didn't originally join the Cardinals as a pitcher. According to Goold, he joined the organization to help develop "an accessible app to allow minor leaguers easier use of data."
Loutos' background in pitching and computer science were a natural fit for the job. He ended up pitching for the Cardinals' Single-A affiliate anyway, and within a year had reached Triple-A.

Loutos repeated Triple-A in 2024 before reaching the majors. He finished last season with a 3.40 ERA in 47 appearances with the Memphis Redbirds. He walked 23 batters and struck out 59 in 53 International League innings.
Listed at 6-foot-5 and 240 pounds, Loutos throws a four-seamer that sits 93 mph an a mid-80s sweeper.

In corresponding roster moves Thursday, the Dodgers placed relievers Michael Kopech and Blake Treinen on the 60-day injured list.
The Dodgers do not have a game scheduled for Thursday. They will kick off their marathon road trip Friday against the Braves. Feyereisen and Loutos will not have to be added to the team's active roster before their first game in Atlanta. It isn't clear how the Dodgers will maneuver their 26-man roster to accommodate the newcomers.
Luis Garcia, Yoendrys Gomez, Evan Phillips, Kirby Yates and Tanner Scott are the right-handed relievers currently listed on the Dodgers' active roster. Alex Vesia, Anthony Banda and Jack Dreyer are the lefties. Ben Casparius has been mentioned as a possible candidate to start during the road trip, but could be used in a bullpen role if not.
Casparius is 3-0 with a 2.91 ERA in 11 games this season — 10 as a reliever. He tossed 3.2 innings against the Pirates in a spot start Tuesday against the Pirates.
