The Marlins claimed Weston off waivers from the Mets on Monday, Will Sammon of The Athletic reports.
Weston made one scoreless appearance in 2026 with the Orioles in what was his major-league debut. The 26-year-old had a 7.18 ERA across 57.2 frames at the Triple-A level this season, though that came with 76 strikeouts.
