Despite all the inspired play that led to the mercurial Australian beating Nadal, the underarm overshadowed all the great shots he produced.

The underarm only served to anger Nadal, even though it was unsuccessful, and Kyrgios' celebration at winning the match ramped up feelings further.

Cue, that handshake...

What a wild match.
