Call it a catharsis. Call it about time. Call it anything you want, but the Rockies badly needed a victory and they got it Wednesday afternoon at Coors Field.

They smashed five home runs — two by Troy Tulowitzki — to beat the San Diego Padres 6-3.

By taking two of three from the Padres, the Rockies won their first home series since May 16-18 when they won two of three against San Diego. It was the Rockies' first series victory of any kind since they swept the Giants in San Francisco, June 13-15. It marked the first time the Rockies won two in a row since they had a five-game winning streak from June 11-15.

"I'm careful about saying when games are must-wins, but all things considered we needed to win that series," manager Walt Weiss said. "We did what we had to do to win the game. We won the game with the long ball, really. (The) bullpen did a nice job. Found a way to win a game."

Tulowitzki, still holding out a glimmer of hope for the postseason, even though the Rockies are 14 games under .500 (39-53), called winning the series "huge."

"It's been a rough first half, no doubt," Tulo said. "The two times I've been to the playoffs (in 2007 and '09), we had to come from behind in the second half. That's what I'm trying to preach to these guys every day, that we can do it."

The Rockies' salvo began early. Newly minted all-star Charlie Blackmon led off the first with a loud solo homer to right-center off San Diego right-hander Eric Stults. It was Blackmon's 14th homer, and all of them have come from the leadoff spot, the most in the majors. His 47 RBIs from the top of the order also lead baseball.
