Buster Posey entered in the bottom of the eighth inning Wednesday with one objective. After an Indians error opened the door, the Giants called on their All-Star with two outs to erase a one-run deficit. Posey did just that, roping a two-run double off the bottom of the left-field wall, giving the Giants a 5-4 win over the Tribe. It was San Francisco's first Interleague series victory of the season.
