What better way to kick off the 2014 Wimbledon championship than with a major upset? The world will know the name of 19-year-old Nick Kyrgios, the Australian teenager that defeated No. 1 Rafael Nadal at the London Grand Slam. Kyrgios is the first teenager to beat the No. 1 at a Grand Slam since the 2005 French Open, when a young Rafael Nadal won against Roger Federer.

Nick Kyrgios' victory was a complete surprise. In fact, not even Nick Kyrgios' mother, Norlaila, could ever imagine that her son would beat the best tennis player in the world. Kyrgios' father and sister were present at Wimbledon to see Nick play, but his mom stayed home because she'd be too nervous to watch her son play live.

“I saw in an interview my mom said [Nadal] was too good,” Nick told the BBC after the match. “That made me a little bit angry.”

Not since 1992 did a tennis player ranked outside the top 100 defeat a No. 1 player. Kyrgios ranked No. 144 when he entered the match. Now, victory over Nadal bumps Nick Kyrgios ranking to No. 66. 

On the other side of the net, Rafael Nadal has been struggling with a Wimbledon slump as it is his third straight loss before the Wimbledon quarterfinals. However, unlike Nadal's loss in Wimbledon 2012 to Lukas Rosol or the loss in Wimbledon 2013 to Steve Darcis, fans did not see a favorite suffering an upset. Instead, 19-year-old Nick Kyrgios' victory hints the arrival of a new star in the sport!

Nick Kyrgios' secret weapon is undoubtedly his monster service. Kyrgios shot 37 aces against Nadal and fired more than 100 aces in his first four matches at Wimbledon. In fact, Kyrgios' booming serves are capable of reaching speeds exceeding 120 mph. 

“I was not able to read his serve during the whole match,” Nadal admitted. “I was not able to put enough returns inside.”
