Ross was released by the Giants on Friday, Alex Pavlovic of NBC Sports Bay Area reports.
Ross has battled several significant injuries since 2016, but the Giants signed him as a non-roster invitee during the offseason. The right-hander allowed three earned runs over 3.2 innings in Cactus League play before spring training was suspended, but he'll be left searching for a new club ahead of the 2020 season.
