It is when your arm is terrible. And to the other guy who compared it to Ramirez improving at third base. The difference is that Ramirez always had the tools to be a good third baseman. You can't learn to have a good arm, you either have one or you don't. Murton's a mediocre defender in left, and is going to have to find a new team if he's ever going to play again. This is the first time you've mentioned arm in your stance against Murton's defense. Like I said, there have been glowing reports of him doing well at AAA, including one play where he ran down a fly ball in foul territory then gunned down a guy at 3rd. We aren't talking about Juan Pierre type arm strength here. And again, we have to relate his ability against what we have. Floyd can barely touch his toes without pulling something anymore, and he's not about to uncork any laserbeams from the corner to gun down baserunners either. And yet, Floyd is playing right in Chicago and Murton is in Des Moines. Those reports must be glowing. So glowing that Jake Fox ended up in Chicago instead of the red headed stepchild. Fox was called up because he could play 1B, and even then,"the Cubs made the decision so it must be right" has not been a strong argument for....well, ever.
