Is Brandon Belt one of the 2011 Giants' best 25 players? On the eve of the season and the start of their World Seriestitle defense that's not very much in question. Actually, if you listen to Bruce Bochy talk about the22-year-old first baseman, Belt's major league credentials probablyare not in question at all. "He's done all he can do," the Giants manager said of Belt beforeTuesday's exhibition in Oakland. "We've told him that. Now it's upto us to make the decision on it."
