Will Smith gave the Los Angeles Dodgers their third game-ending home run in three days, all from rookies, with a three-run shot in the ninth inning Sunday for a 6-3 victory and a spectacular three-game sweep of the Colorado Rockies. Smith, who was called back up to the major leagues earlier in the day, crushed his pinch-hit shot to right-center off Rockies right-hander Scott Oberg (5-1). The Rockies elected to walk veteran Russell Martin to face Smith.
