Tampa Bay Rays acquire Casey Legumina from Seattle Mariners

The Tampa Bay Rays are acquring right-handed pitcher Casey Legumina from the Seattle Mariners in exchange for minor league right-handed pitcher Ty Cummings.

Legumina, 28, was originally selected in the 8th round of the 2019 draft by the Minnesota Twins; Legumina was actually drafted twice prior to signing with the Twins (25th round in 2016 by Toronto & 35th round in 2018 by Cleveland). After quietly working his way up through Minnesota’s system, the Twins would trade Legumina to the Cincinnati Reds for Kyle Farmer in November, 2022. It was with Cincinnati that Legumina made his big league debut, appearing in 11 games during the 2023 season and compiling a 5.68 ERA | 6.73 FIP with a 18.0 K% & 14.8 BB% over 12.2 IP.

Legumina spent one more season with Cincinnati and then was claimed off of waivers by Seattle in February, 2025. Since joining the Mariners, Legumina compiled a 5.43 ERA | 4.15 FIP with a 23.5 K% & 10.3 BB% over 61.1 IP. The Mariners designated Legumina for assignment April 21st following a string of appearances in which he allowed six runs on 10 hits over 4.1 IP.

The cost to acquire Legumina was minor leaguer Ty Cummings, whom the Rays originally acquired from the Mariners as the Player to be Named Later in the Randy Arozarena trade. The 24-year old was originally a starting pitcher in the Rays system but they recently moved him to the bullpen. Prior to this trade, Cummings had made 3 appearances in Double-A, compiling a 1.69 ERA | 4.57 FIP over 5.1 IP.

Legumina is out of options, so the Rays will need to clear a spot on the active roster as well as on the 40-man roster. Marc Topkin is reporting that the move will be made official over the weeknd or on Monday.
