Whitcomb is out of the lineup for Friday's game against the Mets.
Whitcomb has started 10 of 11 games since being called up from Triple-A Sacramento on Aug. 24, but he's yet to take advantage of the playing time with a .431 OPS in 38 plate appearances with the Giants. Osleivis Basabe will handle the hot corner while Nate Furman picks up a start at second base Friday.
