Frenchman Benjamin Bonzi, ranked 50, put up unexpectedly tough opposition against 23rd-seeded Nick Kyrgios.

- It was on the hair.

His level today was incredible, says the Australian.

The hard-serving Kyrgois had not expected the match to be a relatively drawn-out story that ended 7–6, 6–4, 4–6, 6–4.

- To be honest, I did not expect a full-scale war.

It could have gone either way.

I played some really risky tennis in that fourth set to get the win.

I'm just happy to be on.

There was no lack of controversy in the match.

The Australian complained about a smell of marijuana that he claimed was over the pitch, and which risked affecting his asthma.

- It's probably not the best thing to breathe in between points, Kyrgios explained.

The judge went out with a call to the audience not to smoke.

Kyrgios was also heard swearing several times, and was warned in the third set.
