Ruthless Murray sweeps aside Brown

London - New mum Azarenka, Nishikori also reach third round of Wimbledon

Defending champion Andy Murray stormed into the Wimbledon third round with a ruthless 6-3, 6-2, 6-2 demolition of Dustin Brown on Wednesday.

Murray needed only 96 minutes to see off the dreadlocked German on Centre Court as he underlined his return to fitness following a nagging hip injury.

Next up for world number one Murray is a clash with colourful Italian 28th seed Fabio Fognini.

"He started very well, he was coming up with some great drop volleys and really going for the returns," the British star said.

"Once I got the break in the first set, I felt the momentum was with me. I started to see the shots he was going to play a little but quicker and that allowed me to get to some of the drop volleys and come up with some passing shots. The last three games I didn't serve particularly well. But the rest of the match I served well, I was getting a lot of free points there. He wasn't able to attack my second serve like he tries to do so that was positive."

Earlier, new mum Victoria Azarenka continued her comeback bid for Wimbledon glory while Kei Nishikori also reached the third round.

Andy Murray, Rafael Nadal and Venus Williams were made to sweat it out waiting on a sweltering day at the All England Club where players battled soaring temperatures and flying ants in their bid to make the last 32.

Nishikori dug deep to keep his Wimbledon hopes alive as the Japanese ninth seed ground out a 6-4, 6-7 (7/9), 6-1, 7-6 (8/6) win over Ukrainian qualifier Sergiy Stakhovsky.

Despite reaching at least the quarterfinals of the other three Grand Slams, Nishikori has never been beyond the fourth round at Wimbledon.

He next faces Spanish 18th seed Roberto Bautista Agut who ousted German qualifier Peter Gojowczyk.

Former world number one Azarenka, playing her first Grand Slam tournament since giving birth to first child Leo in December, knocked out Russian 15th seed Elena Vesnina.

The 2012 and 2013 Australian Open champion, in her fourth match back, won 6-3, 6-3, taking her record over the Russian to 8-0 without dropping a set.

The Belarusian, 27, could become the first mother to win the Wimbledon singles since Evonne Goolagong Cawley in 1980.

"Travelling is a little stressful for me, travelling with a baby. I want to make sure that everything is okay. But overall, it's just great. It's really fun that I'm able to go home and spend time with my son," she said.

Azarenka next faces British wildcard Heather Watson who also upset the form book. The world number 102 downed Latvian 18th seed Anastasija Sevastova in straight sets.

Nadal, the 2008 and 2010 champion, is looking to reach the third round for only the second time since he finished runner-up in 2011 when he faces fellow left-hander Donald Young of the United States later.

Fresh from winning a historic 10th French Open, Nadal is looking bury memories of the 2015 second round defeat to Brown, his last appearance at the All England Club.

France's Jo-Wilfried Tsonga, the 12th seed, made short work of Italian qualifier Simone Bolelli in the sizzling heat, winning in straight sets.

Fans shielded their faces from the sun with towels, programmes and napkins as temperatures reached 29 degrees Celsius (84 degrees Fahrenheit).

Tsonga was one of several players bothered by an invasion of flying ants. "That was strange... it was in my nose and in my ear," he said.

Gilles Muller won a gruelling five-set encounter with Czech qualifier Lukas Rosol. The 16th seed from Luxembourg won the decider 9-7.

US 24th seed Sam Querrey and Britain's Aljaz Bedene also won their second round matches.

Meanwhile seventh seed Marin Cilic, the 2014 US Open champion, was battling Germany's Florian Mayer for a spot in the third round.

Five-time champion Williams is trying to concentrate on tennis against the backdrop of the impending legal action she faces back home in the United States over a fatal car crash.

The 37-year-old veteran, devastated by the incident, broke down in tears on Monday when talking about the crash. She was facing Chinese rising star Wang Qiang on Court One.

Czech 22nd seed Barbora Strycova lost to Japan's Naomi Osaka, who awaits Williams or Wang.

Two-time champion Petra Kvitova, the bookmakers' title favourite, continues her comeback from six months out recovering from a horrific knife attack in her home with a match against Madison Brengle of the United States.

Eighth seed Dominika Cibulkova and 27th seed Ana Konjuh of Croatia will face each other in round three after coming through their last 64 matches.

French Open champion Jelena Ostapenko and second seed Simona Halep were among those waiting to start their matches.
