I'll end barren spell: Murray

British number one Andy Murray wants to win the Australian Open for his family.

The 22-year-old Scot is aiming to claim his maiden grand slam success after beating 14th seed Marin Cilic 3-6 6-4 6-4 6-2 in yesterday's semi-final at Rod Laver Arena.

Murray will play the winner of today's last-four clash between world number one Roger Federer and Jo-Wilfried Tsonga in Sunday's showpiece.

With two days to prepare, the weight of expectation on the fifth seed to end Britain's 74-year wait for a male grand slam champion is likely to build.

Murray, of course, is desperate to end that barren spell but admitted his motivation is for his family first.

"I want to win it for the people that I work with, for my parents who helped me when I was growing up," said Murray, whose mother Judy has been a permanent fixture among his court-side entourage.

"Then I want to do it for British tennis, and for British sport as well would be excellent.

"But the pressure that I feel doesn't come from the people that are around me. They obviously are happy with anything that I do. But I want to win for them first."

Murray does not expect the pressure from Britain to weigh too heavily on him in any case during the next two days, simply because of the distance from home

"You don't really feel it that much," he said.

"Wimbledon is a bit different, especially in the lead-up to the tournament. But when you're away you don't take any notice of it.

"There's no newspapers that I would read over here. It's not really on the TV that much.

"So I'll just kind of avoid it."

It will be the second time Murray will play in the final of a major after he was beaten by Federer at the 2008 US Open in straight sets.

On that occasion rain in New York had forced Murray to play his semi-final against Rafael Nadal over two days and he did not finish until the day before the final.

This time Murray will have more than 48 hours to prepare and, while he admitted he will have to find ways to occupy himself, he is happier with this scenario.

"I'd rather be in this position than what happened at the US Open," he said. I played three days in a row. In a slam, that almost never happens to anyone. So, physically, I'm going to be in good shape, that's for sure.

"I just need to make sure that I practise properly the next few days, practise enough. I'm sure I'll be fine."

Defending champions Serena and Venus Williams defeated Cara Black and Liezel Huber 6-4 6-3 to win the Australian Open women's doubles title today maintaining the partnership's perfect record in grand slam finals.

The second-seeded Williams sisters continued their dominance over Zimbabwe's Black and American Huber, overcoming a sluggish start under bright sunshine at Rod Laver Arena to win in 86 minutes and seal their 11th grand slam doubles title.

Laura Robson reached the final of the Australian Open girls' championships with a straight-sets win over Kristyna Pliskova of the Czech Republic today. The Briton cruised to a 6-3 6-1 triumph in 65 minutes, converting five of her 13 break opportunities.
