Step 1

1 passes to 2 since 5 is poaching the lane and immediately goes upline. 3 is there to simulate the "Ace."

Step 2

For drill's purpose: 4 realizes (s)he is beat and can't catch up to 1 going upline so yells "SWITCH".

Step 3

Hearing "SWITCH," 5 drops off and goes after 1 while 4 slides over to mark 2. 3 comes into handler position since 1 left.

Step 4

1 goes to Ace and 3 gets the dump swing.

Step 5

Repeat drill.
