VIDEO: Nick Kyrgios Aces Rafael Nadal on Quick Underhand Serve at Wimbledon

The second round of Wimbledon is underway and Nick Kyrgios is already deep into his bag of tricks.

As Kyrgios was preparing to toss the ball in the air for a normal serve, he quickly hit the ball underhand to secure the set with an ace.

The third-ranked Rafael Nadal was completely unprepared and could do nothing but watch the ball bounce in front of him for the point.

After winning his 12th career French Open, Nadal is looking to conquer Wimbledon for a third time. If he wants to be successful, he'll have to get past a rival in Kyrgios.

If one thing's for certain, it's that Kyrgios won't go down easy. He's already shown he'll do whatever it takes to steal a point against the favored Nadal.
