Storm Hunter's doubles win comes with an extra couple of scoops of intrigue, while busted courts and Nick Kyrgios's mixed messages cause confusion.

Here are five quick hits from day 11 at Melbourne Park.

1. Double, double toil and trouble: Sun will burn, and court will bubble?

With the singles quarterfinals getting underway at 12pm AEDT, there was a period of an hour when the outside courts were in the full spotlight, including Australian Matthew Ebden, who is second seed along with Rohan Bopanna.

They were playing Argentinian sixth seeds Máximo González and Andrés Molteni and, at first, everything seemed normal.

The match was on serve, with the Argentines leading 2-1 until the change of ends, at which point Ebden's thumbs started pricking — or perhaps more accurately, his feet.

In the service box, the Aussie noticed the court was starting to blister and bubble.

As Ebden said: "If the serve hits this it's a problem," with Bopanna illustrating the point by dropping the ball on the offending area, and the ball not bouncing.

The thing is, it wasn't a particularly hot start to the day, around 27 degrees Celsius, although there was a storm early in the morning and perhaps some rain got under the covers to create the issue.

Nevertheless, it was a bit of an issue and led to the match being suspended for about an hour while officials fixed the court, with the contest resuming on Margaret Court Arena.

2. Mixed messages from Nick

"The reality is, there is a part of me that knows my time in the sport may be over. And I'm OK with that."

Those were the words from the pen (keyboard, whatever) of Nick Kyrgios in Nine's newspapers on Wednesday morning.
