LONDON (AP) -- For the third year in a row, Rafael Nadal made an early exit from Wimbledon after a stunning loss to a player ranked 100th or lower.
Nick Kyrgios, a 19-year-old wild card from Australia with a world ranking of 144, served 37 aces and used a fearless go-for-broke style -- he even hit a winning between-the-legs shot -- to beat the No. 1-ranked Nadal 7-6 (5), 5-7, 7-6 (5), 6-3 and reach the quarterfinals on Tuesday.
On a day when former champion Maria Sharapova was eliminated in the fourth round and Serena Williams could barely hit a ball and had to pull out of a doubles match with a viral illness, Krygios made the biggest splash of all.
Playing in his first Wimbledon and second major, Kyrgios is the first player outside the top 100 to defeat a No. 1 at a Grand Slam since No. 193 Andrei Olhovskiy downed Jim Courier in the third round at Wimbledon in 1992.
Kyrgios served out the match against two-time champion Nadal at love, hitting an ace on match point. He dropped his racket to the Centre Court turf and held his head in his hands in amazement. He did a little dance to celebrate.
Kyrgios is the first man to get to the quarterfinals in his Wimbledon debut in 10 years, the first teenager to defeat a No. 1 at a Grand Slam since a 19-year-old Nadal beat Federer at the 2005 French Open, and the lowest-ranked player to defeat Nadal at any Slam.
For Nadal, a two-time Wimbledon champion and 14-time major winner, it marked another shocking loss at the All England Club. In 2012, he was ousted in the second round by 100th-ranked Lukas Rosol. Last year, he fell to No. 135 Steve Darcis.
The 6-foot-4 (1.93-meter) Australian struck 70 winners, compared to 44 for Nadal. He dominated with his serve, with a fastest delivery of 133 mph (215 kph). He hit a casual winner between his legs from the baseline in the second set.
Kyrgios will next face eighth-seeded Milos Raonic, the first Canadian man to reach the Wimbledon quarterfinals since Robert Powell in 1912. He beat No. 10 Kei Nishikori of Japan 4-6, 6-1, 7-6 (4) 6-3.
Roger Federer kept up his bid for a record eighth Wimbledon title, beating Tommy Robredo 6-1, 6-1, 6-4 to reach the quarterfinals without the loss of a set.
Sharapova, the 2004 champion, saved six match points before falling to Germany's Angelique Kerber 7-6 (4), 4-6, 6-4 in a fourth-round match that lasted 2 hours, 37 minutes.
Kerber will next face Canada's Eugenie Bouchard, the only woman to reach the semifinals this year at both the Australian Open and French Open.
