The Colorado Rockies (6-6) begin a six game road trip tonight against the Milwaukee Brewers (6-7) in Miller Park at 6:10 MT (TV: Root Sports).  Right-hander Jhoulys Chacin (0-1) is expected to take the mound for the Rockies, with right-hander Shaun Marcum scheduled to start for Milwaukee. Struggling Rockies shortstop Troy Tulowitzki is expected to be back in the lineup after a night off on Wednesday.

Tulowitzki admitted that his six errors -- matching his total from all of last season -- have started to affect the way he approaches his game.

"I'm taking the field and thinking about it," said Tulowitzki. "I never thought about defense [last year]. I just go out there and play, and if I made an error, I made an error. ... But I wasn't worried about it. So, yeah, I think about it. It's in my head. I'd be lying if I said it wasn't in my head. I think about it because I care."

The Brewers won six of the last nine meetings a year ago to take the season series for the first time in five years. The Rockies had won each of the previous four season series dating back to 2007.
