The 3 progressive rules to deal with players rushing the net.

1.Hit to the open space
Get the ball away from the closest danger.  Open space gives you time to set up for rule number 3.

2.No open space? Hit down the middle
Take away the angle by getting it down the middle. If you can get it low they must hit it up against gravity.

3. Now lob or pass
If you can move forward inside the baseline pick your passing shot and go for it.  If not lob yourself out of trouble.
