Day 10 Notable Scores

No. 1 Novak Djokovic def. No. 8 Milos Raonic

Even after failing to drop a set thus far in the tournament, there was no telling how Novak Djokovic would fare against the big serve and aggressive play of No. 8 Milos Raonic. But let it be told that Djokovic didn't skip a beat.

It took less than two hours for the Serbian to wrap this one up, winning the first set in a tiebreaker before cruising down the stretch in a 7-6 (7-5), 6-4, 6-2 victory. 

Raonic entered the tournament with a whopping 99 aces in just four matches, but he couldn't continue his dominance in service against Djokovic. He did hit 15, but that was about 10 less than he averaged in the earlier rounds.

To nullify his service, Djokovic dominated at the net in winning 17 of his 18 net points. That, along with an 89 percent clip on first serves won, allowed the Serbian to waltz to victory.

Even in facing a top foe, it's safe to say the Djoker had his sights set forward in the closing moments. Up next is a semifinal appearance against Stan Wawrinka, whom he's playing for a third straight year in Melbourne, and he's seemingly ready, per the Australian Open:

Wawrinka got the best of Djokovic in last year's quarterfinal meeting, ending a streak of three straight Aussie Open titles. If Djokovic wants to make up for that, he'll need to bring his best yet again.

No. 5 Kei Nishikori came into the quarterfinals on an absolute tear, but Wawrinka reminded him who the defending champion is in Melbourne.

The Swiss star put on a clinical display of dominance Wednesday, thrashing the fifth-seeded Nishikori in straight sets 6-3, 6-4, 7-6 (8-6) to put away the Japanese phenom quickly and advance to another semifinal.

A big serve was used to Wawrinka's advantage. He blasted 20 aces for the match and won 86 percent of his first serves while Nishikori aced just six times. Wawrinka also maintained a massive edge in winners (46-23). 

As you'd expect from Wawrinka's incredible aggression, he committed more unforced errors than his opponent, but it didn't give Nishikori any room to mount a comeback. Although Nishikori battled back from match point after match point, he couldn't win the tiebreaker and force a fourth set.

Nishikori got the best of Wawrinka last time out in the U.S. Open, but Wawrinka made the convincing statement Wednesday that Melbourne is still his. However, the big test that everyone is waiting for is still yet to take place between him and Djokovic in the semifinals. 

Madison Keys def. No. 18 Venus Williams

American 19-year-old phenom Madison Keys' coming-out party in the 2015 Australian Open is officially on, as the unseeded player toppled No. 18 Venus Williams in a three-set thriller Wednesday.

She seemingly took over the match early on and looked to run away with things, taking the first set 6-3. But when Williams mounted a comeback in the second, it looked like it could swing either way in the final moments.

But Keys' solid play shone through, as she hit a favorable 34 winners on the match to Williams' 10. Her return game was on point, relegating Williams to winning just 30 percent of her second serves as Keys took the assertive route.

It was just another incredible display for Keys against a top foe after toppling No. 4 Petra Kvitova earlier, but the chief test stands next as she faces Venus' sister and top-seeded Serena Williams, per Adam Zagoria of SNY.tv:

Whether she gets drubbed by Serena or finds a way to pull off the upset, Keys has already made her claim as the best young women's tennis player in the world. She'll be so much more than just that, however, if she finds a way to beat Serena.
