If you want to throw higher on a tennis match, push down x & the square button together, don't push it down that hard because if you do it will be a out.
Superpowerful Superstar Hit!
Once you've filled up the star underneath you, press R1/L1. Once you've did this, you should have a superstar hit. But, if you press X & Square at the same time while you have your superstar hit activated, it'll become superpowerful and head upwards! Note:If you are on doubles tournament/match, be Tails and use his superpowerful superstar hit on the front person. He/She should hit the tennis ball way out of bounds! Try it!
