Scouting Report: Rhylan Thomas
Seattle Mariners | LF
Overall
Summary
26-year-old left-handed outfielder Rhylan Thomas was claimed off waivers by the Houston Astros from the Seattle Mariners on May 9, 2026. Thomas was designated for assignment by Seattle after struggling in Triple-A Tacoma with a .260/.313/.328 slash line over 31 games in 2026. He made his MLB debut in 2025 with the Mariners, appearing in 3 games with minimal production (1-for-8, .125 average). Originally drafted 11th round by the Mets in 2022, he was traded to Seattle in July 2024. Thomas was optioned to Triple-A Sugar Land by Houston and represents depth for an injury-plagued Astros outfield. He brings a solid contact bat and speed (6 stolen bases in 31 games), with a career .301/.352/.388 Triple-A slash line. Hunter Brown was moved to the 60-day IL to clear the roster spot.
