The biggest concern for me is that few if any hitters are improving under Popkins.....guys that are supposed to be proven major league hitters like Farmer, Vazquez, Santana, Buxton and to a lesser extent Castro look absolutely clueless right now. Julien has taken a step back. Wallner looked lost. The only guy that you could say has improved is Jeffers. There is something fundamentally wrong with the approach the team is taking right now, and that comes from the hitting coach.
