Aaron Cook hasn’t won a playoff game. This time, he knows what to expect.In his only postseason start, Cook took the loss in the deciding Game 4 of the 2007 World Series against Boston. He’ll probably pitch Game 2 of the NL division series next week.“I know the intensity is a lot higher. It is a different situation,” Cook said. “When you can keep things simple and realize it’s just another baseball game, you’re able to go out there and execute. I’m not going to change anything.”Rocktober: Act 2Todd Helton declined to answer questions comparing this year’s team to the 2007 squad, which won 90 games, now the second-most in franchise history, and entered the playoffs as the NL wild card after beating San Diego in a play-in game.“This is a good ballclub,” he said. “We’ve got depth and experience, and we’ve done this before. We’ve poured champagne on ourselves before, and once the party is over, we know how to get back to work.”Etc.The Rockies went 51-31 at Coors Field, tied for the second-best home mark in franchise history. … Colorado drew 2,665,080 fans, the most since 2002. … Troy Tulowitzki had the wildest clubhouse celebration, raining powder and chocolate milk on his teammates. … Jason Giambi on his eighth postseason: “You show up every spring training to have an opportunity to play in October.
