In the middle of any game, your pitcher will naturally start to lose juice. 
However, you do not have to change pitchers. Try to throw strikes as much as 
possible until you have absolutely no juice remaining. You will not be able to
see any red in the straw. Obviously the pitch target will now be very large. 
Choose any pitch. Aim the pitch directly for the kid's head. The ball should 
be on his head or very close to it. Click to throw the pitch, and even if the
shaded region is not in the strike zone, the ball will still be a strike.
