Day two of the Australian Open kicked off in good spirits – courtesy of the Aussie crowd who were still on a high after a night of Australian domination on court.

While the Special Ks – Thanasi Kokkinakis and Nick Kyrgios – had a well-deserved day off the court (apart from a brief training session), there was plenty to keep crowds interested.

• Daily Deuce: day one
• Special Ks lead the way for Australian tennis

Here’s what people were talking about:

Nike admits to playing dirty

We’ve picked up on something interesting about the players sponsored by Nike, other than their rising star status (Kyrgios and Kokkinakis are both decked out in Nike threads) – the bright colours and garish patterns are, well, pretty darn distracting.

So distracting, in fact, that they’ve led some to question the fairness of the get-ups, given a lot of them share a similar colour scheme to a tennis ball.

Nike itself hasn’t even attempted to deny any wrongdoing, instead choosing to highlight the clothes’ “disruptive patterns” as a technical advantage.

“The spring 2015 Nike Tennis collection was conceived to utilise striking colour choices and disruptive patterns as a competitive advantage for performance tennis,” a statement on the brand’s official site says.

Foul play or pioneering design?

David Ferrer mouths off

You might have noticed something interesting about ninth seed David Ferrer other than his ferocious on-court tactics.

He’s essentially the Miley Cyrus of the tennis world.

How so? The Spanish star hits every ball back with his tongue hanging out of his mouth, indicating intense focus.

That, or he’s spent too much time watching Miley’s catchy film clips.

The motion also brings to mind Aussie cricketer Brad Hogg, who also struggles to keep his tongue in his mouth.

Someone get these people a Listerine campaign.

Berdych in love

There’s nothing quite like young love in the summertime.

Czech player Tomas Berdych took a break from his intense schedule to announce his engagement to his girlfriend, model Ester Satorova.

To celebrate, the pair took a romantic walk through Melbourne’s Botanic Gardens.

The pair, who have been dating since 2012, didn’t exactly get some one-on-one time, pulling large crowds and photographers during their stroll.

However, the happy couple weren’t fazed by the attention and happily posed in front of the cameras for all to see.

What a shame they’re so unattractive.

The tournament’s official colour

It appears as though sartorial standards have reverted back to the year 2006 because fluro is well and truly cool again.

More specifically, fluro green has made a comeback in a major way, with the majority of players favouring the fairly obnoxious shade for their on-court appearances.

While Kei Nishikori is adopting a slightly more subtle approach in a Uniqlo shirt, Australia’s Kyrgios is embracing the colour head to toe.

The colour, although visually arresting, makes sense for a group of people who – let’s face it – already stand out from the crowd.

After all, their futures are so bright, they’ve gotta wear shades.

#BelieveInTheSleeve

If you’ve been scanning social media throughout the tournament, you might have stumbled across a confusing trending hashtag: #BelieveInTheSleeve.

Well, be confused no more! The hashtag is designed to support Canadian youngster Milos Raonic, who is known for his unusual choice of attire on court.

The 24-year-old has one long sleeve and one short sleeve, a look he has previously blamed on “injury”.

However, Raonic is injured no more and we suspect the sleeve might now have more to do with a bit of good old superstition.

During the Brisbane International, Raonic admitted as much.

“It started after I got hurt here last year,” he told reporters.

“I didn’t play for many weeks. I started playing in Indian Wells. And just because I wasn’t able to play for a while my arm was sore, so I was using a cream on my arm for massaging and stuff.

“I had to play with long sleeves, and being a basketball fan I saw that they play with compressions sleeves. I thought it was a better way to cover up.

“Since then it stuck around. Some of my team believe that it helps on the compression on the muscles. For me it’s just a habit.”

Sure it is, Milos. Sure it is.
