The writers and editors of TENNIS.com pick the winners of all four Australian Open semifinals.

Victoria Azarenka [3] vs. Kim Clijsters [11]

Peter Bodo, Senior Writer: Clijsters
Azarenka has been striking the ball savagely, but Clijsters has had an aura of invincibility ever since she survived quadruple match point against Li Na.

Ed McGrogan, Online Editor: Azarenka
Clijsters hits bigger, but Azarenka is more consistent. That didn’t work for Caroline Wozniacki, but Vika actually has offense, too.

Richard Pagliaro, Senior Editor: Clijsters
Embraced by the crowd and empowered by her edge in athleticism, agility, and experience, "Aussie Kim" should prevail—if she can manage her nerve and her ankle holds up.

Stephen Tignor, Senior Writer: Clijsters*

Azarenka has been more solid throughout, but Clijsters at her best has more game, and more Slam experience.

Petra Kvitova [2] vs. Maria Sharapova [4]

Peter Bodo, Senior Writer: Sharapova
Kvitova's day will come, but the way the veteran Sharapova has been knocking out opponents, it’s hard to imagine anyone beating her.

Ed McGrogan, Online Editor: Kvitova
The Russian has been more impressive thus far, but her serve is like a ticking time bomb. Kvitova can do the rest.

Richard Pagliaro, Senior Editor: Kvitova
Sharapova has been sharper and is the better competitor, but Kvitova is the more complete player and can advance if she plays with purpose and passion.

Stephen Tignor, Senior Writer: Kvitova
Kvitova has more power; Sharapova is the more seasoned competitor. She also has the most damaging weakness, her serve.

Rafael Nadal [2] vs. Roger Federer [3]

Peter Bodo, Senior Writer: Federer
Federer has been on fire ever since he failed to take down Novak Djokovic at the U.S. Open, whereas his great career rival has been struggling, and took a licking in their last meeting.

Ed McGrogan, Online Editor: Federer
Federer couldn’t have asked for better preparation; with his major chances dwindling, a loss to a still-shaky Rafa would be crushing.

Richard Pagliaro, Senior Editor: Federer

He's been unbeatable since the U.S. Open, and if Federer can combat Nadal's fail-safe play—the lefty forehand to his one-handed backhand—he can return to the final.

Stephen Tignor, Senior Writer: Nadal
They’re both in good form, but history says that when Nadal plays Federer, Nadal usually wins.

Novak Djokovic [1] vs. Andy Murray [4]

Peter Bodo, Senior Writer: Djokovic
As far as the form of these two goes, the similarities between last year and this year at this tournament are striking. Nole wins, but it will be a closer match.

Ed McGrogan, Online Editor: Murray
Not an easy pick, but I’m changing my tune because of Djokovic’s taxing last two wins. A new year is upon us.
*
Richard Pagliaro, Senior Editor: Djokovic
*
The defending champion can play more offensive tennis, owns the best return of serve in the game, and has dropped just one set this tournament.

Stephen Tignor, Senior Writer: Djokovic
Murray is sharp, but we’ve seen him that way before and he’s never won. We’ve seen Djokovic that way before and he has.
