What happened: The Miami Marlins claimed right-handed pitcher Cameron Weston off waivers from the New York Mets on Monday. The transaction adds bullpen depth to Miami's 40-man roster as early offseason moves get underway.

Why it matters: Weston brings a swing-and-miss forkball that served as his primary putaway pitch at the Triple-A level. For the Mets, placing Weston on waivers clears space on the 40-man roster ahead of winter roster reshaping.

What to watch: Miami faces upcoming roster deadlines ahead of the winter meetings as teams set their 40-man rosters to protect eligible players from the Rule 5 draft.
