Player will flye:

When your opponent hits a pop-fly to the outfield
don't catch it. Instead pick it up and run it in 
by holding Z and C-up. Then press the following C
buttons to throw to bases. Right, Up, Left, Down,
Left, Up, Down, Right, Up, Left, Down. You should
hear the crowd boo. On the next hit don't pick it
up. Instead repeatedly tap A or B and your player
will fly.
