Jamie Murray admits he has his eyes on a Wimbledon title after combining with new mixed doubles partner Jelena Jankovic to reach the quarter-finals.

The 21-year-old Davis Cup player, older brother of injured British number one Andy Murray, continued to uphold the family honour despite crashing out of the men's doubles.

Murray and Jankovic, the world number three, followed up their second-round win over third seeds Mark Knowles and Zi Yan with a 6-3 7-6 (7-1) win over 14th seeds Julian Knowle, of Austria, and Tiantian Sun, of China.

"It's a chance to win a grand-slam title and I don't see why not," said Murray. "I don't think there are any real favourites.

"Today was probably our best match and hopefully tomorrow we'll be even better.

"The mixed doubles is a bit of a lottery. It depends on how the girl plays and Jelena played very well, which is probably the reason we're here.

"We beat the number three seeds. That's good work, isn't it? I don't see why, if we kicked them out, we can't progress further."

The Scottish-Serbian pair will now meet ninth seeds Marcin Matkowski, of Poland, and Cara Black, of Zimbabwe, for a place in the semi-finals, where they could meet British pair Alex Bogdanovic and Melanie South.

Bogdanovic and South, who knocked out top seeds Mike Bryan and Lisa Raymond in the second round, will play their quarter-final against Rogier Wassen and Jun-Jang Chan on Saturday.

Murray's title prospects increased after his defeat in the men's doubles enabled him to concentrate on one event.

He and American partner Eric Butorac went out in the third round to Czech Republic duo Lukas Dlouhy and Pavel Vizner, the French Open runners-up, who won 7-6 (7-5) 6-3 3-6 6-2.

Murray said: "We were maybe a bit unlucky in the first set when we lost the tie-break. We gave it our best shot - it just wasn't enough."
