MELBOURNE, Australia - The bottom half of the Australian Open draw concludes the quarterfinal match-ups in Melbourne, featuring the much-anticipated clash between six-time champion Serena Williams and Johanna Konta, the in-form semifinalist from last year. No.5 seed Karolina Pliskova also hopes to continue her unbeaten run in 2017 against Cinderella story Mirjana Lucic-Baroni, who is into her first major quarterfinal in nearly two decades. 

We preview all the Day 10 matchups right here on wtatennis.com.

Wednesday, Quarterfinals

[5] Karolina Pliskova (CZE #5) vs Mirjana Lucic-Baroni (CRO #79)
Head-to-head: Pliskova leads, 3-2
Key Stat: Both Pliskova and Lucic-Baroni are playing in their second Grand Slam quarterfinals (Pliskova, 2016 US Open, Lucic-Baroni, 1999 Wimbledon).

Pliskova made her first 17 Grand Slam appearances without making the second week, but the Brisbane International champion is making up for lost time in her second straight major quarterfinal since reaching the US Open final.

It was a much longer drought for Lucic-Baroni, who needed 18 years to back up her breakthrough run at the 1999 Wimbledon Championships after a mix of personal and financial problems kept her off the tour for almost a decade.

The 34-year-old veteran takes on Pliskova for the first time since the 2015, when the two split their two meetings that season; Lucic-Baroni lost their most recent encounter in a third-set tie-break at the Dongfeng Motor Wuhan Open.

Pliskova has dropped just two sets all season, emerging victorious from a 10-8 final set against Latvian youngster Jelena Ostapenko to brush aside No.22 seed Daria Gavrilova in front of her home crowd.

Can Lucic-Baroni win the battle of big hitters to continue her fairytale run, or will Pliskova continue her newfound dominance at majors and reach another semifinal?

Karolina Pliskova

[9] Johanna Konta (GBR #9) vs [2] Serena Williams (USA #2)
Head-to-head: First meeting
Key Stat: Konta has dropped serve twice in four matches (tournament leader).

With defending champion Angelique Kerber out at the hands of CoCo Vandeweghe, Serena Williams suddenly found herself in a solid position to reclaim the No.1 ranking from her rival. To do it, she'll also need to take home the Open Era record of 23 Grand Slam titles and her seventh Down Under.

Standing between her and the semifinals is an unfamiliar foe in Johanna Konta, the fastest rising force in women's tennis since her initial 16-match winning streak in the summer of 2015.

Konta has been ruthless through four rounds, knocking out former No.1 Caroline Wozniacki and 2015 semifinalist Ekaterina Makarova en route to her second straight quarterfinal in Melbourne.

Serena has taken out on-fire opponents in the past; can she solve the unflappable Brit on Rod Laver Arena, or will Konta keep up her potentially Slam-winning form into the final four?

Ivan Dodig, Sania Mirza

Around the Grounds?

The women's and mixed doubles events are rounding into form, and both feature doubles No.1 Bethanie Mattek-Sands. The American rejoins Lucie Safarova to take on the unseeded Japanese duo of Eri Hozumi and Miyu Kato. Meanwhile, top seeds Caroline Garcia and Kristina Mladenovic will need to turn around from their three-set thriller over Aussies Ashleigh Barty and Casey Dellacqua to play No.12 seeds Andrea Hlavackova and Peng Shuai, who dispatched reigning Olympic champions Ekaterina Makarova and Elena Vesnina in two tight sets on Tuesday.

In mixed, No.2 seed Sania Mirza will partner Ivan Dodig for a second day in a row as they try to reach a second straight Australian Open semifinal; aiming to stop them are an unseeded pair in Gabriela Dabrowski and Mirza's countryman, Rohan Bopanna.
