Of the 37,000-plus people at AT&T Park on Saturday night, only one fully appreciated what Buster Posey was going through.
It wasn’t Buster Posey.
Oh, he’ll gain clarity soon enough. Posey made his much anticipated season debut for the Giants on Saturday, with three run-scoring singles in the Giants’ 12-1 throttling of the Arizona Diamondbacks. It wasn’t his major league debut — he played sparingly as a September call-up last season. But it was his first experience as a player expected to do heavy lifting for a big-league team with playoff aspirations.
