Giants signed C Andrew Knizner to a one-year contract.
Knizner latches on with San Francisco as a backup behind Drew Cavanaugh for the final two months of the season after Daniel Susac hit the injured list with fractured kneecap earlier this week. The well-traveled 31-year-old hit free agency after opting out of his minor league deal with the White Sox last week. He hasn’t appeared in the majors since getting into 33 games for the Giants last year.
