Murray unequivocal about need to avenge loss to Young

One of the world No 4’s lowest moments of a generally impressive 2011 came in Indian Wells in March when he lost to Young, who was ranked well outside the top 100 at the time, in his opening match.

Murray, suffering from post-Australian Open final malaise, followed that up with an equally disappointing defeat by Alex Bogomolov Jr in his first match in Miami before rediscovering his form in the clay season.

Asked if he was the sort of person who thought about revenge, Murray said, smiling: “Yeah, I do.

“I was in a pretty bad place around Indian Wells, Miami time. It was a tough, tough part of the year for me. It’s not so much revenge against Donald, it’s more for the situation I was in there and making sure that I can move on from that.

“Winning against Bogomolov in Cincinnati was very important for me. The match against Young won’t be any different.”

While it was a moment Murray will want to put behind him, the Indian Wells victory was a huge result for Young, once the great hope of American tennis written off as an under-achiever.

The left-hander won the Australian Open junior title in 2005 as a 15-year-old, at that stage the youngest to do so, and had already been playing on the pro circuit for a couple of years when he followed that up with the Wimbledon junior title in 2007.

Young broke into the top 100 later in the same year, after reaching the third round of the US Open.

But the teenager’s progress abruptly stalled and then he started to go backwards as he struggled on the Challenger Tour. Not until this year have signs emerged that Young, now 22, may be ready to live up to his potential, with the American consistently winning matches and reaching the semi-finals at an ATP World Tour event in Washington last month.

Serena Williams breezed into the quarter-finals of the US Open with a comfortable straight-sets dismissal of Serbia’s Ana Ivanovic.

The 28th-seeded American is chasing her fourth title at Flushing Meadows and remained on course with a powerful 6-3 6-4 win over the former world No 1.

Anastasia Pavlyuchenkova reached her second grand slam quarter-final of the season with a hard-fought 5-7 6-3 6-4 victory over seventh seed Francesca Schiavone.

Serbia’s Janko Tipsarevic reached his first grand slam quarter-final with a 7-5 6-7 (3/7) 7-5 6-2 victory over former world No 1 Juan Carlos Ferrero.
