Australian Open 2013, day five: live Williams ekes out a 15-30 lead, forcing Sharapova into consecutive, rare errors. But two unforced errors on the forehand gives Sharapova the edge. The best point of the match ensues, both hitting with force, before Williams again nets on the forehand. WILLIAMS* 1-6, 1-3 SHARAPOVA Mrs Williams is shaking her head in disbelief, hiding behind her sunglasses and rightly so. Sharapova eases to three break points in next to no time. Williams can't get a first serve in for good measure. But she does rally to 30-40, receiving warm applause in doing so (rather like a hapless first round opponent winning a game against Federer in the old days). That turns into a cheer as she reaches deuce. Know what? She wins five points in a row to take the game! WILLIAMS 1-6, 0-3 SHARAPOVA* Yes, another game racked up for the Russian. Seventeen of the last 20 points won now. Williams is completely rattled. The focus has gone. This should be over in 15 minutes. This is quite staggering from Sharapova, who breaks Williams to love. She ends it with two sizzling winners, one either side of the hapless American. Is this the best Sharapova has ever played, we wonder? WILLIAMS 1-6, 0-1 SHARAPOVA* 6-1and 1-0 up is clearly not enough for the Russian. She ends her latest game romp with a thumping "C'MON ON" thanks to an ace down the line. Moreover, she has only summoned 44 per cent first serves in, so she is being helped by Venus too. WILLIAMS* 1-6 SHARAPOVA Two more sizzling winners in this one. First, she sends Williams to both sides, who can then only punch her return mid-court. Like a hare, Sharapova latches onto it. Williams then sends a good serve out wide, but Sharapova is tasting this ball like a more than decent bottle from the Maragaret River. First set after half an hour. All too easy. WILLIAMS 1-5 SHARAPOVA* Sharapova is utterly impressive out on Rod Laver. Her serve and direction is right in sync as she coasts to within one game of the first set. 08.40 More from Djokovic, who has gone on the attack over Lance Armstrong: I think it's a disgrace for the sport to have an athlete like this. He cheated the sport. He cheated many people around the world with his career, with his life story. I think they should take all his titles away because it's not fair towards any sportsman, any athlete. It's just not the way to be successful. So I think he should suffer for his lies all these years. WILLIAMS* 1-4 SHARAPOVA Williams notches up the first game against Sharapova in this year's Open. After 28 games on the trot, Sharapova finally relents as Venus holds to 15. Williams has her game face on. WILLIAMS 0-4 SHARAPOVA* Sharapova races to 30-0 before sending down her first double fault of the night. This, though, is a one-way stroll. Wiliams is getting utterly harangued on the wide ball, with Williams netting every time. Four love up, 18 minutes gone. We're seeing a former multiple grand slam champ getting battered here. WILLIAMS* 0-3 SHARAPOVA Sharapova, jogging around and clearly fired up, is latching on to Williams, who looks downtrodden already, with ease. The American has her at 30-15, but a double fault and a clean winner with the Russian standing way inside the baseline is enough for yet another game notched up. 08.25 More on Novak Djokovic, who has yet to drop serve in three dominating wins at this year's Open and has only had five break points against him in 43 service games. Very Sharapova-like. After beating Radek Stepanek, the top seed will next face either American 20th seed Sam Querrey or Swiss 15th seed Stanislas Wawrinka in the last 16. Radek loves the big stage. You saw how much fun he had. I also had a lot of fun playing. It was a very entertaining match. WILLIAMS 0-2 SHARAPOVA* Sharapova eases to 30-0 before Venus unleashes a fearsome return on the Russian's first serve for an equally blistering winner. Williams is taking to Sharapova's second serve like a duck to water and she now has a break point with a glistening winner down the line. The Russian is sent wide twice but at the crucial juncture, Williams nets with Shara scrambling for position. Two points later and Sharapova has banked her 26th game on the trot. WILLIAMS* 0-1 SHARAPOVA An ominous start from Maria Sharapova, who has rattled off her 25th game in a row by breaking Venus Williams in the opener on Rod Laver. They say this one is all about the serve, but judging by Shara's two double bagels already, we might need only 12 games here. 08.10 One stat attack for you ahead of the off: the last time Sharapova, 25, and Venus Williams, 32, met in a Grand Slam came at at Wimbledon in 2007, when the latter prevailed. Six years on, it will be Venus to serve. 08.05 So, what to expect tonight on Rod Laver? After serving up a 'double, double bagel', second seed Maria Sharapova could find herself packing her bags for her next tournament on Friday after she meets Venus Williams in the third round.Sharapova has barely been pushed in her successive 6-0 6-0 victories over Olga Puchkova and Misaki Doi and while Williams has slipped down the rankings due to injuries and a fatigue-inducing illness, the Russian is not expecting anything other than a taut battle on Rod Laver Arena. There are certainly no secrets coming into that matchup. We've played against each other many times. You certainly know what she's capable of. But when you're out on the court, you're not thinking how many titles she's won or how experienced she is. 08.00 Channel 7, who never fail to disappoint with their choice of words, believe that - according to Twitter - Sharapova and Williams are "glamazons" who "need some sex and sizzle." 07.55 Heather Watson's victor Agnieszka Radwanska will take on Ana Ivanovic, who won the all-Serbian tussle with Jelena Jankovic. Our relationship is fine, it's really good. 07.50 Quick results wrap: Eighth seed Janko Tipsarevic, garish sunglasses and all, has beaten Julien Benneteau 3-6, 6-4, 2-6, 6-4, 6-3. South Africa's Kevin Anderson beat Fernando Verdasco (Spain) 4-6, 6-3, 4-6, 7-6 (4), 6-2 in something of an upset. And Spain's Nicolas Almagro has ousted Jerzy Janowicz 7-6 (3), 7-6 (4), 6-1. 07.40 Here's our man Simon Briggs on Heather Watson's defeat overnight: Even in defeat, Watson can head out of Melbourne in good heart. She has taken 160 extra rankings points here, which could be enough to boost her up as many as ten places from her current position of No 50. 07.35 Japan's Kei Nishikori has reached the fourth round with a straight-sets victory over Russia's Evgeny Donsky. 07.30 The only big clash in tonight's matches comes on Rod Laver. World No 2 and second seed Maria Sharapova plays a blockbuster evening match against seven-time Grand Slam champion Venus Williams and we will be focusing on that one primarily. 07.20 More from the Djokovic's win, who remained on course for a third successive Australian Open title after an entertaining meeting with Radek Stepanek. Stepanek threw some different challenges at the world number one - charging the net on 67 occasions - but Djokovic was still too strong, winning 6-4 6-3 7-5 in two hours 22 minutes. The contest featured a host of wonderful rallies with both players pushed to the limit and Djokovic admitted it was enjoyable to play in. He was chipping and charging, not a lot of players do this any more. A lot of the players stay on the baseline. 07.00 Poland's Jerzy Janowicz has been hit with a $2,500 fine for an extraordinary rant at officials earlier this week. The towering Pole dropped to his knees and repeatedly yelled "How many times?" as he disputed a line-call during his second-round win over India's Somdev Devvarman, and also hit the umpire's chair with his racquet. Sometimes I have a problem to control my emotions, but I'm trying to work on this," he said. 06.50 So Heather Watson's impressive run has come to an end at the hands of in-form fourth seed Agnieszka Radwanska. The Pole won her 12th match in a row and simply had too much guile for the Brit. Here's more from Radwanska: I really had a lot of good matches against top players this year, and I must say I'm really playing good and everything is working. I just hope I keep going. Of course now it's going to be harder and harder, playing against seeded players. 06.30 Good morning and welcome to day five coverage from the Australian Open. No surprises overnight where two-time defending champion Novak Djokovic has duly powered into the fourth round. Never going to be a shock that one really.
