The Seattle Mariners' Rollercoaster Ride with Trent Thornton: A Tale of Ups and Downs
In a surprising turn of events, former Seattle Mariners reliever Trent Thornton has reportedly signed with the Chicago Cubs, as announced by Tread Athletics. This move comes as a twist in the tale for Thornton, who had an eventful journey with the Mariners.
The Mariners had high aspirations for their new reliever, Jose Ferrer, but Thornton's impact was felt immediately upon his arrival. In 2023, he made a strong debut, showcasing an impressive 2.08 ERA and 1.08 WHIP, striking out 21 batters and walking only five in 26 innings. His performance continued to shine in his first full season with Seattle in 2024, where he achieved a 4-3 record and his first career save.
But here's where it gets controversial... Thornton's season took a rollercoaster turn. Despite being a top candidate for high-leverage work, he struggled early on. An appendicitis diagnosis in May sent him to the IL, and upon his return, he faced challenges, including a rough outing that saw his ERA spike to 7.71. However, he bounced back, surrendering no earned runs in 12 of his next 15 appearances.
Unfortunately, Thornton's season came to an abrupt end on July 31st when he suffered a left Achilles tear while covering first base. Despite the injury, he became an iconic part of the Mariners' playoff run. After Seattle clinched a playoff berth, Thornton, on his scooter, circled the bases, cheered on by his teammates and the T-Mobile Park crowd.
And this is the part most people miss... Thornton was one of three players non-tendered by the Mariners following the 2026 season. Across seven seasons with the Mariners and Blue Jays, he amassed a 14-19 record, a 4.38 ERA, and 379 strikeouts. His journey with the Mariners was a testament to the ups and downs of professional sports.
