Sometimes a team needs to blow off steam. When the guy at thecontrols is as good as Troy Tulowitzki, that can mean a lot ofsteam. Held hitless in the first two games of the series, Tulowitzkidoubled twice and singled to launch all three scoring rallies inColorado's 10-2 rout of the Giants on Wednesday. Matt Cain didnot survive the fifth inning and allowed six runs in his firstloss. The Giants would have made a boomingnoise by sweeping the Rockies at Coors Field for the first time innine years. As it was, they won their fourth consecutive series andcompleted a 4-2 trip.
