The Giants selected Haase's contract from Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports.
Haase's selection comes as a corresponding move to Daniel Susac (elbow) being placed on the 10-day injured list along with Jose Butto (arm) being transferred to the 60-day injured list. Haase has slashed .250/.300/.472 across 40 plate appearances in nine games for Sacramento to begin 2026. He'll serve as the backup catcher to Patrick Bailey with Susac down.
