When you and your opponent fill up your point bar, wait until your opponent uses Power Blast. Then, strike the batter out with Big Heat and you will get 100,000 points for a Big Strike Out. You must do this a few times.

If you have Big Heat when the other team has Power Blast, use the Big Heat. If you strike the batter out with Big Heat, you will get an additional 10,000 skill points (enough for a Power Blast).
