The 2012 Australian Open has been exciting so far.
And the women have provided plenty of entertainment as well, leading to some potentially exciting Day Eight action.
Let's take a look at five bold predictions for Day Eight action.
1. Lleyton Hewitt Will Upset Novak Djokovic
Hewitt is playing some great tennis right now. He's already beaten two ranked opponents at the 2012 Australian Open and now has his sights set on the No. 1 player.
Hewitt will be playing in front of his home country fans in Australia, something that should give him a slight boost.
He's never won the Open, and he's running out of time in his career. Look for him to play some of the best tennis of his life as he tries to upset No. 1 and advance to the quarterfinals.
2. Serena Williams Will Lose
Williams hasn't been playing her best the past couple years. Now, she's faced with the task of stopping a hot player in Ekaterina Makarova.
Makarova has been breezing through this tournament despite being unranked.
If Williams gets flustered, as she often does, she could end up getting upset by Makarova.
3. Andy Murray Will Struggle Against Mikhail Kukushkin
Murray always makes things difficult for himself in major tournaments.
By not putting away lesser opponents, he fatigues himself for future matches. That's a big reason he's never won a Grand Slam title.
Look for him to end up beating Kukushkin, but not until the fifth set.
4. David Ferrer Will Win in Straight Sets
Ferrer is playing well right now and has historically done well against Richard Gasquet.
Ferrer holds a 5-1 advantage when the two play and won in straight sets against Gasquet in 2009.
Look for that domination to continue on Day Eight of the Open.
5. Ana Ivanovic Will Upset Petra Kvitova
Kvitova won Wimbledon last year and made it to the quarterfinals in Australia.
But she's still young and inexperienced at Grand Slam events.
Ivanovic will use her experience and superior hard-court play to pull off the upset and advance to the quarterfinals.
