What's the point though of bringing him up if he's just gonna go back if/when he struggles? If you are gonna bring him up, he needs to stay and not get yo-yoed. Because, IMO, one call-up and send down doesn't constitute a yo-yo effect. Now, if it happens more than once in a season, then maybe the argument can be made. Murton and Cedeno had some yo-yo effects going on this year. But testing the kid out at the start of the season to see if he is ready, and sending him down until September if he proves to not be ready isn't jerking him around. I see your point, but I don't have faith in the Cubs doing that. It wouldn't be much harm in that, and I do think there's a good shot that he will perform well. But as has been mentioned, why not just play the kids who have earned it (Cedeno, Murton) and let Pie wait a year. Everyone will be better off from it. There is also the possibility he'll come up and, gasp, play well enough to stick with the club. It does happen from time to time. Of course, it never happens on the North Side...
