Victoria Azarenka will look to continue her torrid form down under on Day 10, but she’ll face her toughest test to date. We preview both quarterfinals from the lower half of the draw here.

Wednesday, Day 10
Quarterfinals

[7] Angelique Kerber (GER #6) vs. [14] Victoria Azarenka (BLR # 16)
Head-to-head: Azarenka leads, 6-0
Key Stat: Azarenka has conceded just 11 games in four rounds.

All signs in Melbourne point to Victoria Azarenka’s first trip to a Grand Slam semifinal since the 2013 US Open. One simply can’t deny that the Belarusian, a two-time champion here, has had a stiff wind in her sails since the season began. She’s reeled off her first 18 sets of 2016 and only once dropped more than three games in a set. Azarenka’s scintillating form and burgeoning confidence adds up to a very stiff challenge on Wednesday for No.7-seeded Angelique Kerber. The German will face Azarenka for the seventh time on Wednesday, and she’s hoping to reverse her fortune in what has been a very lopsided head-to-head up until now. But hope springs eternal for Kerber, who is playing with house money after saving a match point in her first-round match against Japan’s Misaki Doi. “I was actually with one leg on the plane back home, but I won the first match with the match point down,” Kerber said on Monday after reaching her first career Australian Open quarterfinal. “So, yeah, and then after I was playing much better. I’m feeling good, and right now I will try to take my next match and play again good tennis.”

It’s been all Azarenka on the scoreboard for these two thus far, but the No.14 seed does not for one second underestimate the danger of facing a perpetually engaged fighter like Kerber. And she surely remembers that Kerber pushed her to the brink in a thrilling three-set encounter at the US Open last September. “It’s exciting,” said Azarenka of the upcoming tussle. “I always look forward to play against her. She gives me always tough matches. I prepare myself for a very tough match because she’s very solid, very consistent, and an amazing fighter. I have to play my best game to beat her, for sure.”

Pick: Azarenka in three

Zhang Shuai (CHN #133) vs. Johanna Konta (GBR # 47)
Head-to-head: Tied, 1-1
Key Stat: Zhang is the first qualifier to reach the quarterfinals at the Australian Open since 1990.

Tear up your predictions, crack open your WTA media guides, and get ready for some crazy emotions, because Day 10’s second quarterfinal features a pair of relatively unknown talents who have already made history in Melbourne. Johanna Konta became Great Britain’s first Grand Slam quarterfinalist in 33 years when she defeated Ekaterina Makarova in the round of 16. Nowhere near the Top 100 at this time last year, Konta has reached the second week of the last two majors and is projected to reach the Top 30 if she reaches the semifinals. But standing in her way will be China’s suddenly surging Zhang Shuai. The 27-year-old was 0-14 at majors prior to qualifying for this year’s Australian Open, but she’s racked up four wins—including a first-round upset of No.2-seeded Simona Halep—to reach the quarterfinals. Can Zhang possibly keep this dream run going? Or is Konta’s ascension set to continue?

Buoyed by her improbable run, Zhang is starting to believe that a deeper run is her destiny. “This time feeling like maybe God will bless me,” an elated Zhang told reporters of her eight-year wait for Grand Slam success. “If I can wait for long time, eight years, I can one time win a lot of matches at a Grand Slam.” Though also thrilled with her recent rise, Konta is less surprised that her time has come. “I’ve always said I do not believe in kind of a light switch moment,” she told reporters. “Everything happens for a reason. My journey has been the way it has been for a reason. That’s to accumulate the experiences that I’ve had. I cannot give you a moment where I said, Oh, yeah, that’s where it started, because it’s been ongoing ever since I started playing.”

Pick: Konta in three
