I highly doubt that they move him from 3B during the season as I've said numerous times. I don't think this is an issue so much with Gamel/Braun/Weeks/Fielder/whomever as it is an organizational flaw in developing defense or moving players to a spot where they will be successful. For example, putting LaPorta in the OF made no sense, he's a 1B/DH, always has been, maybe it worked for him and increased his trade value I don't know. Hart bounced around multiple positions, Braun had to pickup a new position in MLB, Weeks has taken YEARS to approach average, Fielder... well he'll likely never be average despite being a pretty good athlete for his size. Nothing in Gamel's lines suggest he's a platoon player, he could hit LHP and provide ROY quality offense tomorrow if the organization had been more aggressive and moved him to a different position (regardless of need at 3B). I understand what's best for the team is Mat staying at 3B, but that's not what I'm speaking to, nor is that X's point about the bench and the lack of options against LHP. If the organization is/was adamant about Weeks playing 2B and Gamel at 3B, then get them the help they need early. Go to them in the off-season to work with them, or bring them to AZ on the team's dime, it doesn't matter. Just get them the support they need to develop their game to the best of their potential. Weeks defense was never addressed until MLB (and no roving infield instruction just doesn't cut it) and Gamel never got help till AA when he finally made some progress. Constant repetition is the only way to relearn movements, telling someone the right way they should do it isn't going to get it done and never has.
