Just like they did in 2007, the Colorado Rockies open the playoffs in Philadelphia as the hottest team in the National League.
Only this time, they might be without the hottest pitcher in baseball.
Lefty Jorge De La Rosa, who went 16-3 after losing his first six decisions, will test his tight left groin in a bullpen session Tuesday in Philadelphia in an experiment that will go a long way in determining the rest of the Rockies' rotation.
De La Rosa reported feeling better Monday but everything hinges on his side session in Philly.
