The Colorado Rockies are learning to love life on the road under new manager Jim Tracy.

Aaron Cook pitched shutout ball into the seventh inning and closer Huston Street shook off a ninth-inning home run by Ryan Braun to earn his fourth save in as many games, lifting the Rockies to a 5-4 victory and three-game sweep at Milwaukee yesterday.

That's eight straight wins, all on the road, for the Rockies, who completed a four-game sweep of St. Louis earlier this week - shredding two of the NL Central's best over 7 days.

"I think we should just go straight to Seattle," Cook said.

Instead, the Rockies will face the Mariners at home, where they're 9-14 this season.

"Now we have to take this home with us to our fans and get our house in order," Tracy said. "Because we're a much better team at home than 9-14."

Colorado is 10-4 under Tracy, who took over for the fired Clint Hurdle on May 29.

But it's not like the Rockies were completely adversity-free: Catcher Paul Phillips nearly got run over by the Miller Park "Racing Sausage" mascots as he walked out of the dugout.

And Phillips got booed for it!

"I said, 'Jeez, tough crowd,' '' said Phillips, whose two-run single in the eighth proved to be the difference for the Rockies. "They were more into the sausage race, obviously, than they were the game."

The Rockies selected Tracy's son, Mark, a catcher at Duquesne University, in the 49th round of the first-year player draft.

"We didn't ask for any favors, but I'm proud of him," Jim Tracy said.
