On a historic night of milestones at AT&T Park, San Francisco Giants catcher Buster Posey got a blast simply living in the moment. Posey belted a two-out, two-run home run in the bottom of the ninth inning Wednesday, lifting the Giants to a 4-2 victory over the Colorado Rockies. The win was No. 1,600 in the managerial career of the Giants' Bruce Bochy, who moved past longtime rival Tommy Lasorda and into 19th place on the all-time list. Bochy pulled starter Tim Hudson with a 2-1 lead to start the ninth inning despite the fact the veteran right-hander threw only 87 pitches.
