An easy way to win all the characters easily is to play by yourself and gain A LOT of points. Once you have at least 30 some thousand points, go buy "Pinch Hit Coupons". Once you have at least 15 of these, play in VS mode and when selecting a golf course, go to options and put on the coupons. This will let the computer win for you!
