In my opinion, manual focus is not very effective in action sports especially at the wide open apertures I also recommend. Short sequences at burst speeds will more often result in the better shots. These shots are the bread-and-butter of the F2.8 (and faster) lenses. Best of luck.
Since I will be shooting with a 100mm f2.8 for the pitcher and home plate shots I look forward to trying these suggestions. I guess a 70-200 would be the best compromise lens but I don't have one of those.
