Wilin Rosario singled in the ninth inning and scored the game-winning run on Dexter Fowler\'s sacrifice fly Monday in Colorado\'s 5-4 win over Pittsburgh. The Rockies held a 4-1 lead in the top of the ninth and appeared on their way to a victory, but Rex Brothers (5-2) surrounded a two-out, three-run homer to Pedro Alvarez, tying the score. Rosario came right back in the bottom of the frame with a single off Jason Grilli (1-3), went to third on Jason Giambi\'s pinch-hit single and scored on Fowler\'s fly, salvaging the win for Colorado. Eric Young stroked a two-run double to cap a four-run fifth for the Rockies, who claimed the first of a three-game set. The second-place Pirates remained one game behind Cincinnati in the National League Central despite the loss.
