• Australian Open Plays of the Day

The foot in mouth award goes to...

Kim makes a boob out of Woody
The undoubted highlight of Day Four of the Australian Open was Kim Clijsters' centre-court grilling of Australian doubles legend-turned-commentator Todd Woodbridge over a text message the world No.3 was never meant to see. As 'Woody' started to interview Clijsters on court after her easy victory over Carla Suarez Navarro, Clijsters hijacked the conversation to tell the crowd about the text, cheekily shown to her by former Aussie doubles star Rennae Stubbs. Clijsters revealed Woodbridge had texted Stubbs during the Sydney tournament last week to suggest she might be pregnant again. Not content with that, a grinning Clijsters told the watching world Woodbridge's reasoning behind his theory, that "she looks a bit grumpy out there and her boobs have gotten bigger!" The pair had a good-natured embrace but an embarrassed Woodbridge could only end the interview saying: "Well that's the end of my career!"

Youzhny's perfectly timed tweener
Mikhail Youzhny was pushed to five sets by surpise-packet Blaz Kavcic, but not before he hit the shot of the tournament so far. Set point up in the second set, Youznhy did well to retrieve a drop shot at the net before Kavcic responded with a well-placed lob. Youzhny wheeled his sprint around in a 180-degree arc, chased down the ball and sent back a top-spin tweener that cleared Kavcic's reach at the net and dropped inside the baseline in the far corner.

Tomic's top tactics
Australian teenager Bernard Tomic is the only local left in the men's draw and he will next meet Rafael Nadal in a match that will capture the imagination of the host nation. Tomic, at 18 years old and ranked 199, is definitely a hot prospect for the future of the game. His on-court intelligence has been praised as a key to his game, a big compliment considering his age. It was clear to see as he progressed to his first Grand Slam third round with victory over Feliciano Lopez. Tomic outsmarted a veteran of the game with a patient gameplan, most evident at 2-2 in the first-set tie-break when he exhibited great restraint before Lopez cracked in a 32-shot rally.

Flu better watch out
Rafael Nadal came to Melbourne battling the effects of flu that hit him hard in Doha last week. He had an easy time of things in round one and after disposing of Ryan Sweeting with the minimum of fuss, the world No. 1 fired a warning to his rivals by insisting his body is almost at full tilt. "I had a difficult week last week in Doha, it seems like every day is a little bit better, I don't have nothing, I hopefully [am] totally recovered," he said.

The lion goes to sleep
David Nalbandian showed the heart of a lion to beat home favourite Lleyton Hewitt 9-7 in the fifth set in the first round. But the lion lost his roar in the second set as the Argentine offered almost literally nothing as he toppled out of the tournament 6-1 6-0 2-0 to Richard Berankis. Hewitt is probably sat at home, admittedly curled up on the sofa alongside his beautiful wife, looking on and thinking about what might have been.

Batter up
World No.1 Caroline Wozniacki used her day off to good effect, as she traded her racket for a bat and a pair of pads as she made her way to the MCG for a spot of cricket. The Dane is a confirmed fan of football, but she added another string to her bow when getting bowling tips from Peter Siddle and a batting masterclass from Aaron Finch. It is unlikely that Wozniacki will give up the day job, but she was invited to watch the Victoria Bushrangers in action on Sunday.

Murray mania catching fire
Last year's beaten finalist is making good progress in the tournament and his fans were out in force as he treated them to a real show of authority against Illya Marchenko. There was nothing flashy about Murray's play, he did not need to dig deep or go for big shots, but what he did do well was serve. Sixteen aces flew off the racket of the Scot and he won 79% of points on first serve. A show of authority that the main challengers for the title will take note of.

Del boy driven potty
Juan Martin Del Potro is feeling his way back into tennis after suffering a horror 2010 on account of a wrist injury. He had more downs than ups against Marcos Baghdatis, including an injury scare to that wrist when he lost control of his racket. But he had one of those moments when you want the ground to open up and swallow you during the second set. He set up a point superbly and with Baghdatis out of position after throwing up a gentle lob, Del Potro went in for the kill and duly smashed the ball into the net. A horror moment.
