1.Daisy (overall great, i hit homeruns with her)
2.Funky Kong (god at everything exept running)
3.Baby DK (good at everything)

I think Bowser Jr. is the best overall in the new one (not even close in the old one)
Daisy is good in the old one but I am thinking Dry Bones for #2
but I think I have to give the third spot to either Hammer Bro or Kritter

In the old one it goes like this
Bowser (best hitter in the game easy)(terrible starting pitcher I don't care what anyone says. You better get rocked if you start him. First base all the way, or catcher, maybe even third if you wanna be risky, but it's not like anything too bad could happen)
Hammer Bro (2nd best hitter in the game smaller target but good players can do it, great arm and decent in the field because reguardless of his fielding stat if you can play at all you will not make many errors. Maybe one a game.
Daisy could be 3rd overall but you really could give this spot to a couple of people like mario, luigi, yoshi. BUT I choose Daisy cauz she's smooth. You see them hands?!?! Quick throw (in the old game) her slides and dives almost give me a boner.

i like wario for number 1 and hammer bro for number 2 and baby DK for number 3.
