Dodgers Acquire Ryan Loutos, Claim J.P. Feyereisen

The Dodgers have acquired right-hander Ryan Loutos from the Cardinals in exchange for cash and claimed righty J.P. Feyereisen off waivers from the Diamondbacks, reports Fabian Ardaya of The Athletic. The Loutos trade was previously reported by Derrick Goold of the St. Louis Post-Dispatch. The Dodgers moved righties Blake Treinen and Michael Kopech to the 60-day injured list to open 40-man roster spots for the two pickups.

Loutos, 26, has had a somewhat unusual trajectory to the big leagues, as explored in this profile from Goold last year. Due to his computer science background, the Cards hired him to develop an app to help minor leaguers use data, and let him pitch as well. “I know what I need to do to improve. I know what I could do,” Loutos said. “But I also know from their shoes what they see: ‘OK, let him play for a while. See what happens. Worst-case scenario, we maybe offer him a job in the front office. Best-case scenario, maybe he’s in the big leagues someday.’”

So far, the playing part has worked out okay. He made his major league debut last year, though it was brief. He tossed 2 1/3 scoreless innings over three appearances. From the start of 2023 to the present, he has logged 134 innings on the farm with a 5.10 earned run average, 24.2% strikeout rate and 10.7% walk rate.

Feyereisen, 32, has a much longer big league track record. In 2021, he tossed 56 innings between the Brewers and Rays with a 2.73 ERA. He managed to top that performance in 2022, tossing 24 1/3 scoreless innings, with a 29.1% strikeout rate and 5.8% walk rate. However, a shoulder injury intervened and stopped him from building on those numbers.

He underwent shoulder surgery and was traded to the Dodgers ahead of the 2023 season. He hasn’t been able to fully re-establish himself in the majors since then. He eventually spent that entire 2023 season on the IL, not making an official appearance anywhere. The Dodgers shuttled him to Triple-A and back in 2024. He only got to pitch 11 big league innings, with an 8.18 ERA in those. His 5.48 ERA in Triple-A wasn’t especially impressive either.

He was outrighted off the roster last year, allowing him to elect free agency and sign a minor league deal with the Diamondbacks coming into 2025. He got called up a couple of weeks ago after posing a 0.96 ERA in Triple-A. He then allowed two earned runs in two innings for the Snakes before getting designated for assignment and put on waivers.

More to come.
