DENVER -- Giants catcher Buster Posey threw his hands down and shook his head at the ball Chris Iannetta launched right inside the left-field foul pole. Iannetta's solo home run in the seventh inning ended a rare pitchers' duel at Coors Field on Wednesday night as the Rockies beat the Giants, 1-0, to complete a three-game sweep.
In only the 10th 1-0 game in Coors Field history, the Rockies (44-43) moved one game above .500. They have won six of their last seven.
Rockies left-hander Tyler Anderson (6-3) twirled his second straight gem, following his eight scoreless innings against the Dodgers on June 29.
