Nick Kyrgios (No. 26) defeats Milos Raonic (No. 7)

Kyrgios typically the most powerful service man on the court and was again Friday, but Kyrgios had trouble early on dealing with Raonic's serve. Raonic hit 12 of his 18 aces in the opening two sets, pushing the tempo and keeping Kyrgios on his heels.

But all along, Kyrgios remained in control with his own serve and got back into the match with it, as Brian Phillips of Grantland noted:

All in all, Kyrgios smashed 34 aces in a daunting display of superiority. After dropping that opening set, he rattled off the final three—one in a convincing tiebreaker—to knock off the second top-10 seed in the men's draw after Rafael Nadal went down Thursday. 

Unsurprisingly, Kyrgios kept it real with a brief statement, per Wimbledon:

Pointless to say, most 20-year-old players would be rattled by the moment—especially after getting this far in such an esteemed event. But Kyrgios isn't your average 20-year-old. This is already his second career quarterfinal appearance at Wimbledon, his third at a Grand Slam and his second in 2015.

Of course, this time last year, Kyrgios fell to Raonic in the quarterfinals. With a test against No. 21 Richard Gasquet looming, perhaps the Australian has made the improvement necessary to force a semifinal clash against potentially Novak Djokovic.
