Casilla (2-3) picked up the win after his fourth blown save of the season, allowing a run on one hit and one walk in the ninth inning Wednesday against the Rockies. Casilla has Buster Posey to thank for a walk-off home run to get him off the hook after spoiling Tim Hudson's fantastic start. It was his first blown save since taking over as closer for the Giants. The right-hander hasn't been as sharp in August, sporting a 4.70 ERA over eight appearances.
