LOS ANGELES -- Not only did the Colorado Rockies pull themselves out of a nosedive this weekend, they may have kept the Dodgers' hopes of an NL West pennant race alive with their first three-game sweep at San Francisco in six years.Less than a week ago, the Rockies were plunging out of contention with an eight-game losing streak, but after three comeback wins up north, they've won five straight and they're only two games behind the Dodgers for second place going into the opener of a three-game series at Dodger Stadium on Monday night.
