Ryan Loutos Bio
Ryan William Loutos, born on January 29, 1999, is an American professional baseball pitcher currently in the Seattle Mariners organization. He has previously played in Major League Baseball (MLB) for the St. Louis Cardinals, Los Angeles Dodgers, and Washington Nationals, and made his MLB debut in 2024. A right-handed reliever, Loutos has built his career as a hard-throwing arm out of the bullpen after a distinguished amateur run in Illinois and at Washington University in St. Louis.
Over the course of his early professional career, Loutos has moved through several organizations in a short span, reflecting both the demand for relief pitching and the constant roster churn across the majors. His journey from undrafted free agent to big-league pitcher has been marked by steady work in the Cardinals’ minor league system, a first major league appearance in 2024, and a series of transactions in 2025 that took him from Los Angeles to Washington and eventually to Seattle.
Early Life and Background
Ryan William Loutos was born on January 29, 1999, in Barrington, Illinois. He grew up in the Chicago suburbs and attended Barrington High School, where he starred on the baseball team. As a senior in 2017, he posted a 0.47 earned run average (ERA) with 92 strikeouts across 59 innings pitched, a strong finish that helped establish him as a college recruiting target.
After high school, Loutos enrolled at Washington University in St. Louis, where he played college baseball and continued to develop as a pitcher. As a senior in 2021, he went 11–1 with a 1.33 ERA over 13 starts, an outstanding campaign that put him on professional scouts’ radars. During the summers of 2020 and 2021, he also played collegiate summer baseball for the Fond du Lac Dock Spiders of the Northwoods League, gaining additional experience against high-level amateur competition.
Path to Baseball
Despite his strong college record, Loutos went unselected in the 2021 Major League Baseball draft. He signed with the St. Louis Cardinals as an undrafted free agent on July 22, 2021, beginning his climb through the minor leagues. He made his professional debut that summer with the Palm Beach Cardinals, going 1–2 with a 5.56 ERA over 22⅔ innings, and quickly earned promotions as he refined his command.
By 2022, Loutos was moving between three affiliates, the Peoria Chiefs, the Springfield Cardinals, and the Memphis Redbirds, showing the Cardinals organization that he could handle a full season of work. Over 46 games and two starts across the three clubs, he went 3–6 with a 3.96 ERA and 72 strikeouts across 63⅔ innings, and he was selected to play in the Arizona Fall League for the Salt River Rafters after the regular season. In 2023, he opened the year at Springfield before a quick promotion to Memphis, and across 50 relief appearances he struck out 84 batters in 73 innings, building a profile as a high-strikeout reliever.
Ryan Loutos Career
Early Career (2021–2023)
Loutos’s first three professional seasons were spent entirely in the St. Louis Cardinals’ minor league system, where he progressed steadily from Low-A Palm Beach to Triple-A Memphis. His swing-and-miss stuff stood out, and his selection to the Arizona Fall League after the 2022 season gave him a chance to test himself against some of the top prospects in baseball.
By the end of 2023, Loutos had established himself as a relief option on the cusp of the majors, with a swing-man profile and a strikeout rate that hinted at a future in the late innings. The Cardinals added him to the 40-man roster in May 2024, rewarding his consistent work in the high minors.
St. Louis Cardinals (2024–2025)
Loutos began the 2024 season with Triple-A Memphis, compiling a 1.72 ERA with 18 strikeouts and four saves across 13 appearances. On May 20, 2024, he was selected to the 40-man roster and promoted to the major leagues for the first time. He made his Major League debut on June 1, 2024, working a scoreless eighth inning against the Philadelphia Phillies in which he allowed one walk and one hit.
Across his rookie campaign, Loutos made three scoreless appearances, allowing only one walk and two hits over 2⅓ innings pitched. He was optioned back to Triple-A Memphis to open the 2025 season, where he allowed three runs in eight innings before being designated for assignment by the Cardinals on April 28, 2025.
Los Angeles Dodgers (2025)
On May 1, 2025, Loutos was traded to the Los Angeles Dodgers in exchange for cash considerations and was initially assigned to the Triple-A Oklahoma City Comets. He was called up by the Dodgers on May 16, and that same night he recorded his first major league strikeout against Tim Anderson of the Los Angeles Angels, a memorable early highlight in a Dodgers uniform.
His time in Los Angeles was brief. Loutos allowed five runs across three innings in two games with the Dodgers and posted a 2.10 ERA over seven appearances with Oklahoma City before being designated for assignment on June 6, 2025.
Washington Nationals (2025)
On June 10, 2025, Loutos was claimed off waivers by the Washington Nationals, giving him another opportunity in the majors. The biggest moment of his season came on June 19, when he recorded his first career win after allowing no earned runs in the 11th inning of a 4–3 victory over the Colorado Rockies. It was his first regular-season decision at the big-league level.
Loutos appeared in 10 games for Washington, finishing his time there with a 12.00 ERA and six strikeouts across nine innings of work. Despite the uneven results, his first MLB win and his continued strikeout ability kept him in the conversation as a usable relief arm.
Seattle Mariners Era (2025–2026)
On November 6, 2025, Loutos was claimed off waivers by the Seattle Mariners, joining his fourth major league organization in a single calendar year. The Mariners optioned him to the Triple-A Tacoma Rainiers to open the 2026 season. On March 31, 2026, he was designated for assignment by Seattle and was released two days later, only to re-sign with the Mariners organization on a minor league contract on April 7, 2026. On April 20, he was placed on the full-season injured list, ruling him out for the entirety of the 2026 season without appearing in a game.

His minor league resume shows consistent strikeout totals, including 84 punchouts in 73 innings in 2023 and 18 strikeouts in 13 appearances during his 2024 stint at Memphis.
