Palumbo (undisclosed) signed a minor-league contract with the Giants on Thursday, Chris Hilburn-Trenkle of Baseball America reports.
Palumbo was claimed off waivers by the Giants on Nov. 5, only to be non-tendered by the club 25 days later. Now back for a second stint with the team, he'll have to prove that he's healthy after being limited to only 6.2 innings in 2021 due to an undisclosed injury.
