Hahahahahahahahaha I really like having Dempster on the team, but man, if he's actually your ace then you're in trouble. I'd still count Z as the Cubs best starter, but I don't know if they have an "ace." ARAMIS! Alot of people throw the term "ace" around a bit too freely, often using it to mean the teams #1 starter. Many teams are devoid of an ace. Others such as the Giants and Phillies have more than 1.
