Rockies power their way to win

Troy Tulowitzki homered for a career-best fourth game in a row, Jason Giambi hit his first home run since coming to Colorado and the Rockies beat the Arizona Diamondbacks, 10-4, Saturday night to get some breathing space in the wild-card race.

The Rockies won for only the second time in seven games, but it extended their wild-card lead over San Francisco to 3 1/2 games.
