I have Colby Rasmus on my team. I was wondering when you thought he might be called up this year and how he looks for this season and the future?

Dave: The hype machine just continues to roll here, doesn't it? There's no denying that Colby Rasmus is one of the best young prospects in the game. Rasmus, a five-tool player who will be a major contributor to all five fantasy offensive categories, is going to be a hitter that fantasy owners build their teams around in the future. He has an incredible left-handed swing, with plenty of power. Add that power to his excellent presence on the base paths, and you have yourself a young prospect who will consistently be a 20-homer, 20-steal player, with the ability and skill set to achieve more. However, with the outstanding play of the Cardinals' outfield this season -- it's pretty crowded right now with Skip Schumaker, Rick Ankiel, Ryan Ludwick, and Chris Duncan -- I don't see a reason for the Cardinals to rush Rasmus. Plus, Rasmus is hitting only .186 through 42 minor league games this season, which means that he's still struggling to find consistency. He'll have to bring up his average before Cardinals management gives him the call. Don't look for Rasmus until rosters are expanded in September, or if there's an injury situation that needs to be addressed immediately.
