I read an article, though I don't remember where, that talked about wrist injuries and lingering effects on the batter. It said that you're looking at a minimum of one year before the hitter's strength starts to come back and something like 18 monts for full recovery. I think the injury in 2006 was still effecting him during at least the first half of 2007. I don't know that he'll ever repeat 2005, since the power numbers were quite a bit higher than what he'd done before, but I think there's potential to get close.
