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.

For the Dodgers, they are likely happy to have some fresh arms, one of which they are already familiar with. With Blake Snell and Tyler Glasnow both on the IL due to shoulder inflammation, they are down to a four-man rotation of Yoshinobu Yamamoto, Roki Sasaki, Tony Gonsolin and Dustin May. The club is keeping Sasaki and Yamamoto on the weekly schedule the pitchers are accustomed to from their time in Japan.

That situation, plus plenty of other injuries, have led to a great deal of creativity in cobbling the staff together. Pitchers like Landon Knack, Justin Wrobleski, Bobby Miller and Ben Casparius have made spot starts. Yoendrys Gómez, recently claimed off waivers from the Yankees, is working a long relief role. Both Loutos and Feyereisen have options, so the Dodgers are adding some arms with some roster flexibility. The team is about to start a stretch of playing ten straight games. After one off-day, they will play another nine straight.

To open spots for those two, Kopech and Treinen hit the 60-day IL. Kopech’s move isn’t especially surprising. He’s been on the 15-day IL all year long due to a shoulder impingement and still hasn’t begun a rehab assignment. Even if he were to start one now, he would need a few weeks as a sort of delayed spring training. He could be reinstated from the IL in a couple of weeks but that doesn’t seem to be likely.

The move for Treinen is more notable. He started the season healthy but landed on the 15-day IL April 19th due to right forearm tightness. This transfer to the 60-day IL indicates the Dodgers don’t expect him back before the middle of June. He is 36 years old, turning 37 in June, and has a recent history of arm injuries. He only tossed five innings in 2022 due to shoulder problems and then underwent surgery which wiped out his 2023 campaign.

He got back on track last year with a 1.93 ERA in 46 2/3 innings, plus another 12 1/3 postseason innings with a 2.19 ERA, helping the Dodgers win the World Series. The team believed in that bounceback enough to give him a two-year, $22MM deal in free agency, the largest deal for a reliever going into his age-37 season or older since Mariano Rivera’s deal with the Yankees back in 2010.

Shortly after Treinen landed on the IL last month, manager Dave Roberts described the injury as a “low-grade sprain of the forearm” and downplayed the severity by saying “we’re in the dodged-a-bullet category.” It’s unclear if Roberts was just masking the extent of the injury or if something changed, but Treinen now appears to be slated for an absence of at least a couple of months.
