MELBOURNE (Reuters) - Top seeds Novak Djokovic and Simona Halep advanced to the Australian Open third round on Thursday but Halep was made to work hard for her win over American Sofia Kenin.
Djokovic produced a clinical display to put away Frenchman Jo-Wilfried Tsonga 6-3 7-5 6-4 in a repeat of the 2008 final at Melbourne Park.
It was the 31-year-old Serb’s 16th consecutive win on the Grand Slam stage and he will next face Canadian youngster Denis Shapovalov.
Halep was cruising to victory after leading by a set and a break but Kenin roared back to edge the second set in a tiebreak.
Despite going down a break in the decider, Halep kept her composure to prevail 6-3 6-7(5) 6-4.
It is the first time since Wimbledon in 2009 that all of the women’s top eight seeds have reached the third round at a Grand Slam.
Serena Williams needed just 70 minutes to swat aside Canada’s Eugenie Bouchard 6-2 6-2 as she continued her quest for a record 24th Grand Slam title.
Twice Grand Slam winner Garbine Muguruza overcame Britain’s Johanna Konta 6-4 6-7(3) 7-5 in a marathon match that finished after 0300 local time. The Spaniard will next face two-times finalist Venus Williams.

At 0312 local time early Friday, two-time Grand Slam winner Garbine Muguruza battled past Britain’s Johanna Konta 6-4 6-7(3) 7-5 in two hours and 42 minutes.
“I can’t believe that there’s people watching us at 3:15,” Muguruza said courtside.
“It was very tough. Johanna was playing very good, serving incredibly, big shots. I just tried to fit and hang in there.
“We play for you guys watching, otherwise why are we here. “I’m going for breakfast now!”
In a repeat of the 2008 Melbourne final, top seed Novak Djokovic fired 33 winners to beat Frenchman Jo-Wilfried Tsonga 6-3 7-5 6-4.

World number one Simona Halep survived an almighty scare against Sofia Kenin before she overcame the unseeded American 6-3 6-7(5) 6-4 to reach the third round.
After blasting her way through the first set and racing to a 3-0 lead in the next, 2018 runner-up Halep appeared to step off the gas as she allowed the determined Kenin to level at 3-3 and eventually drag the contest into a decider.
Halep battled hard in the third set and regained control with a decisive break in the ninth game before closing out the match on her second match point in two hours and 31 minutes.
Australian wildcard Alexei Popyrin advanced to the third round after seventh seed Dominic Thiem retired from the contest while trailing 7-5 6-4 2-0.
Last year’s semi-finalist Chung Hyeon, seeded 24th, was knocked out by unseeded Pierre-Hugues Herbert 6-2 1-6 6-2 6-4. Frenchman Herbert meets Milos Raonic next.

Action resumed on the main showcourts at Melbourne following a short spell of rain.
U.S. Open champion Naomi Osaka powered past unseeded Slovenian Tamara Zidansek 6-2 6-4. She plays Taiwan’s Hsieh Su-wei in the next round.

Kei Nishikori was dragged into a five-setter for the second match in a row but the eighth seed dug deep to beat Croatian veteran Ivo Karlovic 6-3 7-6(6) 5-7 5-7 7-6(7).
The Japanese looked in control after taking a two-set lead but the 39-year-old Karlovic did not back down and leveled the contest. Nishikori held his nerve in a tight decider to prevail in three hours and 48 minutes.
U.S. Open semi-finalist Anastasija Sevastova overcame a mid-match blip to defeat Canadian qualifier Bianca Andreescu 6-3 3-6 6-2 and advance to the third round. The 13th seed takes on China’s Wang Qiang next.
