The Marlins designated Gray for assignment Sunday.
Gray lost his spot on the 40-man roster to right-hander Mike Baumann, whom the Marlins claimed off waivers from the Angels on Sunday. A 28-year-old infielder, Gray received brief cups of coffee with the Marlins in May and June but has otherwise spent the entire 2024 campaign at Triple-A Jacksonville, slashing .240/.312/.454 with 17 home runs over 410 plate appearances.
