It would be cool if he could even prove that he can consistently be a starting corner OF in the minors first. Let's put it this way: there's absolutely no reason to rush Colvin or make definitive assumptions about his ability in the majors right now. It's cool that he's knocked out so many HR in such relatively limited playing time, but holy God, the rest of his offense is in this same stretch is mostly appalling and wildly all over the place. They have already called him up to the majors and he is far from struggling. At this point, barring some horrible stretch of him struggling, it would be ignorant to send him back to the minors. Let him work out his problems where he is at. The majors typically aren't the place for a player with this many flaws and who clearly needs a lot of work to be this early. He needs to be starting, and it doesn't behoove the Cubs to pencil him as a starting OF next season. I don't how you can look at his numbers and think he's doing fine. Yes, the home runs are fun, but he's hitting at a clearly unrealistic rate, and they've become almost the only thing that he is able to hit, and that's likely largely due to him not being exposed because of his limited playing time since he added muscle to drive the ball better with. I'm not saying send him back the minors now, because I have the feeling Fukudome will be moved and he'll then be able to get plenty of starts, but if the Cubs hope to see him take the steps necessary to being a full time starting OF then it's the smart choice to have him starting in the minors next season. He still has a ton of work before they can or should just hand him a starting job after this season.
