I like most of your choices. Although I'd make a few changes:Most surprising hitter NL:
Tie - Shane Victorino/Brandon Phillips.....not much was expected from either of these guys. Id rank Phillips as the 2nd best 2b behind Utley, could go 30/30. Victorino went undrafted in most leagues. Im glad I have both
I'd also put Haren up there with Beckett. No one expected him to be this good.
Dye's been even more disappointing than Manny IMO.
