"Triple-A baseball isn't very good" - Giants GM Brian Sabean when asked when Buster Posey would be promoted.
Maybe AAA isn't very good, Mr. Sabean, but Buster Posey certainly is. Yes sir, Posey is hammering Major League pitching now.
As has been mentioned, Buster Posey had a career game last night for the Giants against the Milwaukee Brewers. His first career grand slam and 6 RBI. There's also video of Posey's post-game interview.
