Bernard Tomic has won through to the third round of the ATP Tour’s Acapulco Open in Mexico after downing Frenchman Adrian Mannarino in straight sets, while Nick Kyrgios stormed to victory in Dubai.

World No.23 Tomic beat Mannarino 6-4 6-4 and will now face either American Ryan Harrison or Ukrainian Illya Marchenko in the third round.

Tomic, seeded fifth at the event, is the only Australian remaining in the tournament after Sam Groth and John Millman were knocked out in the first round.

Kyrgios continued his hot run of form with a comfortable straight sets win over Mikhail Kukushkin in the second round of the Dubai Tennis Championships.

The 20-year-old Canberran, who won his maiden ATP event in Marseille last week, brushed aside the unseeded Kazakh 6-3 6-2 to seal a seventh successive victory.

He’ll play third-seeded Czech Tomas Berdych in his quarter-final.

Kyrgios beat the world No.7 in last week’s semi-final in France to avenge his loss to the talented 30-year-old at last month’s Australian Open.

And Berdych said he’s looking forward to facing the enigmatic Australian for the third time this year.

“He’s full of fireworks on the court – in a good way,” Berdych said.

“He’s playing really aggressive. He’s going for a lot of shots, risking a lot.

“For me it’s going to be a big challenge. I have a lot of revenge to get back after last week. I must refocus myself, try to raise the game, and play some good tennis again.”

Novak Djokovic sealed his 700th career win at the expense of Tunisian wild card Malek Jaziri 6-1 6-2.

The world No.1, who joined the tour a decade ago, has a 700-146 career record.

He’s one of three active players to reach 700 wins, along with Roger Federer( 1,067) and Rafael Nadal (775).

“Sounds like I played many matches in my career,” a smiling Djokovic told the crowd.
