After being the team's starting first baseman on Opening Day, San Francisco's Brandon Belt sat for the fourth straight day on Friday. Aubrey Huff has seen time at first base, while right field, another position Belt can occupy, has been played by Nate Schierholtz. Belt is 1-for-11 with five strikeouts thus far in 2012, but has just two plate appearances since April 8. It may be time for the Giants to consider trading Belt to a team in need of a first base prospect.
