MELBOURNE -- Here are the matches to watch on Day 9 of the Australian Open. Tuesday's quarterfinal play begins on all courts at 7pm ET on ESPN2. Click here for the order of play, and see the full TV schedule here.
No. 3 Simona Halep vs. No. 10 Ekaterina Makarova
The first quarterfinal up on Rod Laver Arena on Tuesday features the two most under-the-radar women who happen to be demolishing the competition. Neither Halep or Makarova has lost a set in Melbourne -- they're the only two left in the final eight who haven't dropped a set -- and Halep heads into her second Australian Open quarterfinal on a 9-0 start to the season.
She leads the head-to-head 1-0 with a win over Makarova in New Haven in 2013. Though Halep is the hot hand, there's just something about Makarova in Melbourne (or any other city ending in "Bourne"). The Russian lefty is the only player to ever beat both Serena and Venus Williams at a major (at the Australian Open in 2012 and 2014), though she has has never been No. 1. A win on Tuesday and she'll be into her second consecutive Slam semifinal.
No. 2 Maria Sharapova vs. No. 7 Eugenie Bouchard
The second match on Rod Laver Arena is also the most high profile of all four women's quarterfinals. Is this the year that Bouchard finally solves Sharapova? She is 0-3 against the Russian but the two haven't played on hard court since 2013, where Sharapova won 6-2, 6-0.
But Bouchard comes into the match with a world of confidence. In their only meeting of 2014, Bouchard pushed Sharapova in the semifinals of the French Open before losing 4-6, 7-5, 6-2. That she was able to do that on Sharapova's best surface has to make her believe she can do it here on a quicker hard court, which should feed into her game. Look for Bouchard to try to beat Sharapova to the punch and be the early aggressor in points. If she can have a good serving day, Sharapova's in big trouble.
One interesting note looking ahead to the possible semifinals: Sharapova is a combined 10-0 against Halep and Makarova, while Bouchard is 1-4 (0-2 vs. Makarova).
No. 3 Rafael Nadal vs. No. 7 Tomas Berdych
Australian Open Fashion Hits and Misses
HIT: Maria Sharapova
In a sea of neon, Sharapova's classy pink number hits all the right notes.
MISS: Victoria Azarenka's long sleeve
Rule No. 1 in tennis fashion: Don't dress like the tennis ball.
HIT: Grigor Dimitrov
Black, white, clean -- the best men's kit of 2015.
HIT: Andy Murray
Murray wears the black and bright green combo well, and it's a bit more subdued than some of the other neon colors.
MISS: Venus Williams
2014 was a great year for Venus' EleVen, but their first offering this year is an ill-fitting 70's inspired mess.
HIT: Roger Federer
It's a rare sight to see Federer in fluorescent colors. And rarer still, after his third round loss.
HIT: Roger Federer
HIT: Petra Kvitova
Looking as fit as ever, Kvitova has been wearing this pink Nike kit well.
HIT: Eugenie Bouchard
Youthful and fresh in pink.
HIT: Madison Keys
Just like Bouchard, Nike made the right choice with this hot pink number.
HIT: Ana Ivanovic
Blink and you missed it.
MISS: Kei Nishikori
The lime green color somehow looks old and dirty. Uniqlo would have been better off with something clean and bright.
HIT: Elina Svitolina
A classic tennis look from a classic tennis brand in Ellesse.
HIT: Elina Svitolina
HIT: Agnieszka Radwanska
Clean and fresh in Lotto.
MISS: Caroline Wozniacki
The fit is perfect, but the color and pattern are reminiscent of an old tea towel.
MISS: Caroline Wozniacki
HIT: Rafael Nadal's shorts
Nadal called them his "party pants."
HIT: Milos Raonic
The neon stripe on the socks makes it work.
HIT: Serena Williams
The dream of the 80s is alive in Melbourne. If only she had some leg warmers.
We loved the back detail on the dress as well.
HIT: Simona Halep
A no-nonsense athletic look for a no-nonsense athletic star.
HIT: Thanasi Kokkinakis
It's the most memorable kit of the tournament and a look Kokkinakis worked to perfection in his five set win over Gulbis. Winning makes (almost) everything look good.
HIT: Victoria Azarenka's sleeveless
It's the women's version of Kyrgios' kit. And we like it.
MISS: Novak Djokovic
Djokovic has been alternating between a white shirt and a blue shirt. A boring and disappointing offer from Uniqlo.
MISS: Stan Wawrinka
A boring striped blue shirt? The defending champion deserves better from Yonex.
MISS: Andrea Petkovic
The grey top is great. The skirt is cute too. But put them together and it's a mess.
MISS: Simone Bolelli
Military camo? Really?
The kit doesn't work on Muguruza, either.
MISS: Gael Monfils
Let's put the pumpkin orange away, Asics.
MISS: Michael Russell
Worst kit of the tournament.
MISS: Fernando Verdasco
Is his head rising from the smoke and ashes?
MISS: Tomas Berdych
In the sea of blue that is the Australian Open, let's not add more blue.
HIT: Camila Giorgi
Shorts! A belt! A collar! This is pretty old school and great.
HIT: Nick Kyrgios
It's the fluorescent version of Dimitrov's kit and the 19-year-old has lit it up.
Does Berdych have a chance here? He's been playing lights out tennis through four rounds and hasn't lost a set. But he's also riding a 17-match losing streak to Nadal. Berdych hasn't beaten the Spaniard in nine years. That win came at the Madrid Open in 2006, when Berdych famously shushed the Spanish crowd after scoring the win, something Nadal took great issue with after the match. Berdych has won just three sets off Nadal ever since. If Nadal gets his 18th straight win over Berdych on Tuesday it would be the longest head-to-head winning streak in Open Era history.
Nadal has won their three Slam meetings, most recently a four-set win at the 2012 Australian Open. More bad news for Berdych: Nadal is coming off his best performance of the tournament, a 7-5, 6-1, 6-4 win over No. 14 Kevin Anderson. Nadal and Berdych will be the third match on Rod Laver Arena.
"Doesn't matter what happened in the past. Is different story this time. Different moment for me; different moment for him," Nadal said after his match on Sunday. "I have success against him, but I have the chances to lose against him. I remember 2012 probably I had a very, very tough match against him here. It was close to be two sets to love down. He's a player that is top level."
No. 6 Andy Murray vs. Nick Kyrgios
How much will Murray relish a stadium full of Australians cheering against him as he takes on a 19-year-old upstart? A lot. Murray will try to pick apart Kyrgios' flashy game on the big stage and, in his own way, put Kyrgios in his place.
"I think it obviously will change the atmosphere. Obviously the crowd will be right behind him. Understandably so. They're going to watch him play a lot of matches like this over the next 10, 15 years probably," Murray said after his match on Sunday. "That's just something that I'll have to deal with in my way. I've played a lot of matches. I've played in French Open against French players where the crowd can be very difficult. I've experienced it before, so hopefully I'll deal with it well."
In their only head-to-head meeting, Murray beat Kyrgios 6-2, 6-2 in Toronto last year. Murray hasn't lost to a player ranked as low as Kyrgios since the 2005 U.S. Open when he lost to No. 91 Arnaud Clement.
To pull off the upset, Kyrgios will need a spectacular serving day and a sustained and focused effort. That consistent focus and concentration has been alittle bit difficult for Kyrgios, but he has survived his many lapses so far. He is coming off an emotional five-set comeback win against Andreas Seppi on Sunday night, while Murray has been in very good form through the first week, losing just one set and coming through an incredibly physical three-and-a-half hour win over No. 10 Grigor Dimitrov.
