Australian Open 2016: Results, Highlights, Monday Scores Recap from Melbourne

A day after chalk reigned supreme, some surprise returned to the court Monday at the 2016 Australian Open.

Stan Wawrinka's quest for a second title in Melbourne went down in flames against Milos Raonic, Madison Keys exited quicker than expected against Shuai Zhang, and Johanna Konta continued a career-best run with a win over Ekaterina Makarova.

Wawrinka's loss was undoubtedly the most notable, as he was coming off a 2014 win and a semifinal appearance last year. He and Raonic battled for nearly three hours, with Wawrinka working his way back from two sets down before faltering in the fifth. The two heavy hitters put on an excellent display of power, with Wawrinka's struggles putting his first serves in play ultimately being his undoing.

Winner	Loser	Score
Milos Raonic (13)	Stan Wawrinka (4)	6-4, 6-3, 5-7, 4-6, 6-3
Andy Murray (2)	Bernard Tomic (16)	6-4, 6-4, 7-6 (4)
Gael Monfils (23)	Andrey Kuznetsov	7-5, 3-6, 6-3, 7-6 (4)
David Ferrer (8)	John Isner (10)	6-4, 6-4, 7-5

Raonic, who will be making his second straight quarterfinal appearance in Melbourne, was brilliant on first serves. He had 24 aces and won 79 percent of his first-serve points. While that was juxtaposed by six double-faults, Wawrinka actually eclipsed that number with nine and had only 58 percent of his first serves go into play.

"I've been sick since 10 days now," Wawrinka said, per Ravi Ubha of CNN. "Still trying to get into the second week. Couldn't really be at my top. When you play a top guy like Milos, it's difficult. You need to be 100 percent to have a chance to beat him."

Damien Cox of the Toronto Star offered his take:

Raonic moves on to play Gael Monfils, who defeated Andrey Kuznetsov 7-5, 3-6, 6-3, 7-6 (4). Monfils was dominant throughout, nailing 14 aces, taking nearly three quarters of his service points and winning all but one of his 16 attempts at the net. The 29-year-old Frenchman is in the midst of his deepest run at the year's first major.

“I think I focused great on my serve. I needed to because he was playing very good," Monfils said, per Jake Stevens of the Open's official website. "I’ve had a good first week here—I just hope I can have a wonderful second week, too.”

The other two matches on the men's side went as expected. Andy Murray breezed through to the quarters with a 6-4, 6-4, 7-6 (4) win over Bernard Tomic. The second-seeded Brit had 18 aces in the three-set romp and nearly double as many winners (43) as unforced errors (22). Murray has made the finals four times at this event, but he has been stopped short of winning each time. Nearing three years since his last major win, Murray is certainly playing with a contender's form.

That said, there were cracks in Murray's game. He hit only 57 percent of his first serves in play and allowed Tomic to have nine break point chances. 

“It was a tough match,” Murray said, per Kevin Mitchell of the Guardian. “Both of us had our chances. He fought right to the end, but I just was able to make a few more balls. It was quite a scrappy match. Neither of us played our best tennis at the same time.”

As for how the fans were feeling, well, there was this:

David Ferrer will be the next to try taking down Murray after a straight-sets win over John Isner. Ferrer overcame 18 Isner aces by playing a smart brand of tennis, committing 17 unforced errors to his opponent's 49.

Unforced errors played a huge part in the exit of another American, as Keys made 51 mistakes in her 6-3, 3-6, 3-6 loss to Zhang. Keys looked strong for the most part early on, needing only 32 minutes to take the first set. However, her game soon fell apart. Keys double-faulted four times, failed on seven of 10 break opportunities and didn't take advantage of a 14-to-30 winners-to-errors ratio from Zhang.

Most of this can be blamed on a lingering leg injury. Keys was obviously at less than 100 percent throughout the match, which drew raves from Mark Gottlieb of Fox News:

Zhang, a qualifier, will take on another surprise in Konta during the quarters. Konta ousted the 21st-seeded Makarova despite dropping the first set, coming back for a thrilling 4-6, 6-4, 8-6 victory. The pair combined to double-fault 13 times, and each struggled to finish off break points, but Makarova's 60 unforced errors ultimately caused her demise.

Winner	Loser	Score
Angelique Kerber (7)	Annika Beck	6-4, 6-0
Victoria Azarenka (14)	Barbora Strycova	6-2, 6-4
Shuai Zhang	Madison Keys (15)	3-6, 6-3, 6-3
Johanna Konta	Ekaterina Makarova (21)	4-6, 6-4, 8-6

Zhang had never previously made it past the first round in a major, while Konta's only previous victories were at the U.S. Open.

The victor will take on the winner of Victoria Azarenka and Angelique Kerber in the semis. Both women breezed through their fourth-round opponents. Kerber took an hour and 28 minutes to defeat countrywoman Annika Beck 6-4, 6-0, which was two minutes longer than Azarenka's 6-2, 6-4 win over Barbora Strycova.

Kerber is making her first quarterfinals appearance in Melbourne, while Azarenka is a two-time winner Down Under.

"I feel really happy," Azarenka said, per Stuart Fraser of the MailOnline. "I think enjoying myself on the court really helps me physically to be in good shape."

Health has been a major key throughout Azarenka's career. Her run as the world's top-ranked player was cut short by a series of injuries and inconsistent play, with the former often running concurrent to the latter. Still, there is reason for optimism.

Azarenka won her first title since 2013 at Brisbane earlier this year, taking down Kerber in the final. If history can repeat itself, Azarenka would be well on her way to her first Grand Slam final since the 2013 U.S. Open.
