Milos Raonic Stuns Stan Wawrinka

The 25-year-old Canadian, who had never beaten the French Open champion in four previous meetings, sent down 24 aces and hit 82 winners in the three-hour, 44-minute contest to reach the quarter-finals for the second year in a row. 

Swiss Wawrinka fought back from losing the first two sets to force a decider but was unable to avoid exiting a grand slam before the quarter-finals for the first time since the 2014 French Open. After belting 24 aces and 82 winners, Raonic will now need to back up the 3 hours and 45 minutes spent on court when he faces flamboyant Frenchman Gael Monfils, a four-set winner over Russian Andrey Kuznetsov earlier in the day. Raonic sealed the victory with a simple volley at the net.

"When you play a top guy like Milos, it’s difficult. You need to be 100 percent to have a chance to beat him. Unfortunately, I’ve been sick since 10 days now," says Stan Wawrinka, Swiss tennis player. 

Fourteenth-seeded Victoria Azarenka beat No. 48thranked Barbora Strycova 6-2, 6-4 to clinch a spot in the quarterfinals against No. 7 seed Angelique Kerber.  The two-time Australian Open champion beat Barbora Strycova 6-2, 6-4 in the fourth round Monday -- continuing a three-year sequence of wins against the Czech player, which started in the second round in 2013 and included the third round last year. 

Angelique Kerber has cemented her place in the last eight of the Australian Open with a hard-fought 6-4 6-0 victory in an all-German affair against Annika Beck. Despite a lopsided scoreline, it was certainly no easy feat for the world No.7, who was pushed by Beck early on in a competitive display on Rod Laver Arena. With both women strong on their returns, it was a classic case of match being played in two contrasting halves. 

Gael Monfils has dived headfirst into his first Australian Open quarterfinal with an entertaining 7-5 3-6 6-3 7-6(4) victory over Andrey Kuznetsov. At 3-2 in the second set, the acrobatic Frenchman became airborne as he leaped, racquet-first, to reach a wide forehand at the back of the court. The return missed but the sheer ridiculousness of the attempt embodies everything that endears Monfils to fans around the world.
