The first week of the 2013 Australian Open is history, but thankfully there's one more week of tennis still to play from Melbourne Park.
Day 7 Down Under provided some fascinating results, some as expected and others we didn't see coming. A trio of title contenders in the women's draw saw themselves through to the quarterfinals, while a handful of elite men are bound for the next round.
Here we'll get you caught up on all the latest happenings from the year's first Grand Slam.
Men's Top Seeds Advance, Djokovic Survives
Novak Djokovic is on to the quarters, but not before a Round of 16 scare by No. 15 Stanislas Wawrinka. The Swiss player gave the top seed everything he could handle for five-plus hours. But in the end, it was Djokovic taking the match in five sets, 1-6, 7-5, 6-4, 6-7 (5-7), 12-10.
The match, which began around 8:30 p.m. local time on Sunday in Melbourne, concluded around 1:40 a.m.
In previous action, fourth-seeded David Ferrer of Spain looked like he might have his hands full early but turned up his game and disposed of No. 16 Kei Nishikori in straight sets, winning 6-2, 6-1, 6-4 to advance to the quarters, where he'll play fellow Spaniard Nicolas Almagro.
No. 10 Almagro advanced after eighth-seeded Janko Tipsarevic retired late in the second set of their Day 7 match with Almagro leading 6-2, 5-1. The Serbian suffered a heel injury and was already playing very poorly to start, committing 22 unforced errors. The awkward victory means that Almagro (first time ever in the Aussie Open quarters) will be well rested for his upcoming matchup with his countryman.
In an under-the-radar Round of 16 clash, fifth-seeded Tomas Berdych ousted unseeded South African Kevin Anderson in straight sets, 6-3, 6-2, 7-6 (15-13). The third and final set lasted nearly an hour and a half and was won on the strength of Berdych's first-serve success (80 percent first-serve points won).
Female Favorites Cruise Through Fourth Round
Three of the four female favorites in action on Day 7 won easily in straight sets to advance to the quarterfinals.
Maria Sharapova highlighted the trio of victories, crushing Belgian player Kirsten Flipkens, 6-1, 6-0. The 25-year-old Russian won 81 percent of her first-serve points and smashed 25 winners in the straight-set win that took just over an hour to complete. Sharapova will take on fellow Russian Ekaterina Makarova in the quarters.
Meanwhile, No. 4-seeded Agnieszka Radwanska blew past former world No. 1 Ana Ivanovic, 6-2, 6-4, to advance to the quarters in Melbourne for the third straight year. The 23-year-old Polish star played a brilliant match, tallying seven aces while committing just four unforced errors.
Sixth-seeded Li Na capped a strong day from the women's favorites, taking down 18th-seeded German opponent Julia Goerges. Li won a dramatic first set, 7-6 (8-6), and then went on to win the second easily, 6-1. Her Round of 16 victory was highlighted by 16 winners and a perfect 5-of-5 mark on break-point chances.
Li and Radwanska will play each other in the quarterfinals.
Makarova Upends Kerber to Reach Quarters
Ekaterina Makarova's name likely won't jump out at anyone, but over the last two years the 24-year-old Russian has made some deep runs at the Australian Open. After defeating No. 5 Angelique Kerber in straight sets on Day 7, 7-5, 6-4, she'll advance to the quarterfinals for the second straight year in Melbourne.
The biggest keys for Makarova in pulling off the upset were cashing in on her break-point chances and winning a solid percentage of her second-serve points. She did both, converting four of eight break-point chances and claiming 46 percent of her second-serve points for the match.
Makarova's serve isn't going to scare Maria Sharapova in the quarters, but if she can continue to force more than half of her serves into the body of her opponent, she shouldn't be counted out.
