Noval Djokovic Beaten By Big-serving Reilly Opelka In Quarterfinals Of Brisbane International

Novak Djokovic was beaten 7-6 6, 6-3 by big-serving Reilly Opelka in the Brisbane International quarterfinals on Friday.

Opelka served 16 aces - including one to finish off each set - to earn one of the biggest wins of the American's career.

"I was just focused on my spots," Opelka said. "If I hit them, it's hard to get them back. If there's anyone that can, it's him."

The 37-year-old Djokovic was playing his first tournament of the year. The 24-time Grand Slam champion is preparing for the Australian Open, which starts on Jan. 12 and which he has won 10 times.

"We have nothing to lose coming in against him. He's the greatest player ever," Opelka added. "So you end up playing more free and you take a lot more risk. If you play your normal level or even above a normal level, he's going to win every time. So it's tough in his position because he gets guys that are good players that they roll the dice. And on a on a day like this when a lot of things go my way that's how it works out."
