The Giants designated Bivens for assignment Wednesday, Alex Pavlovic of NBC Sports Bay Area reports.
The move makes room on the Giants' 40-man roster for Duncan Davitt, who was claimed off waivers from Atlanta. Bivens has spent most of the 2026 season in Triple-A, where he has a 4.92 ERA, 1.39 WHIP and a 72:28 K:BB over 75 innings.
