DENVER (AP) — Buster Posey hit a pair of three-run homers, including a tiebreaking drive as part of a six-run eighth inning, and the San Francisco Giants rallied for a 10-5 win over the Colorado Rockies on Saturday after their bullpen blew a lead.
The Rockies were limited to one run over six innings by Madison Bumgarner, but erupted in the seventh against five San Francisco relievers to take a 5-4 advantage.
San Francisco responded right back with six runs in the eighth. Posey led the charge with a towering homer to right-center off Carlos Estevez (1-2).
Posey also hit a three-run homer in the first inning. It was the third multihomer gamer of Posey's career, two of which have now come against the Rockies. His six RBIs tied a career best.
Cory Gearrin (1-0) threw 1 1-3 scoreless innings to earn his first win since May 28, 2013.
