Here is the best team in the game's lineup and positions.
1)Mario- SS 2)Luigi- 2nd 3)Dark Bones- 1st 4)Petey Piranha- C 5)Hammer Bro- CF 6)Boomerang Bro- RF 7)Fire Bro- LF 8)Peach- 3rd 9)Tiny Kong- P
The 3 hammer bros are interchangeable in the outfield and in the batting order, and if T.K. is getting hit a lot, you can move Luigi to 3rd and put T.K. at 2nd and Peach to P. This is my all star team and i have never lost a game with them. Good luck!
