Jason Marquis started the June 25 game, which saw the Rockies score six runs in the top of the ninth and then lose in the bottom of the inning. We don't need to see that happen again, the last part that is. Though, having to score six runs in what could be the last inning of the game is never really a good thing. Sure, it shows the team never gave up, but it also demonstrates either the paucity of run support given to the pitcher up to that point or the lack of good pitching by the losing team.
Cook didn't pitch against the Cubs back in June so this is his first star of the season against the Cubbies. Al's preview at Bleed Cubbie Blue will tell you that Cook is 2-0 in two starts against the Cubs.
