The Giants are optimistic that closer Brian Wilson will be ready for the start of the 2011 season. Doctors confirmed Monday that he has nothing more than a mild strain on his left side. "We are encouraged by the progress he's made," manager Bruce Bochy said. Wilson, who led the majors with 48 saves last year, said he could pitch now if this was the regular season. "If it's a regular-season game, I'm throwing," he said "There's really no point in risking anything by going out and pitching the sixth inning of a spring training game on March 21."
