Chicago Cubs: Tyler Colvin sent to minors - chicagotribune.com No surprise, he needs to play consistently to get out of the funk he is in and doing it in Iowa is the only way. I'm skeptical about calling Campana up though, he's played well but just how much is he really going to play as a 5th outfielder? A guy like that needs to stay in Iowa to continue his development with regular at bats. Reed Johnson has been playing well lately and getting a few starts as the 4th OF already which already was taking away from Colvin's at bats. I guess there aren't many options on the 40 man roster at OF, you have Fernando Perez who is barely hitting .200 right now so they'd have to make a move in order to add someone like Brad Snyder or Bryan LaHair to the 40 man.
