Giants first baseman Brandon Belt has agreed to a $3.6 million, one-year contract that avoided salary arbitration. During batting practice in July before a game at Miami, two Giants accidentally threw balls to Belt at the same time. San Francisco manager Bruce Bochy had his doubts, too, especially when Belt's symptoms returned for a second time. Following Belt's agreement Monday, new third baseman Casey McGehee is the Giants' player left in arbitration.
