Andy Murray believes coach Ivan Lendl's bittersweet relationship with the US Open could help him unlock the door to lifting his first Grand Slam title.
Murray reached his eighth successive quarterfinal at a Major on Monday with a 6-4, 6-4, 6-2 win over big-serving Canadian Milos Raonic as he continued his campaign to end his record of four Grand Slam finals without a trophy.
Lendl, who started to work with the world number three at the start of this year, lost three finals in New York from 1982-1984 until clinching three titles in a row from 1985-1987.
Olympic champion Murray was runner-up to Roger Federer in the 2008 final in what is his only appearance in the championship match at the US Open.
"I've spoken to him about playing in big events, you know, losing to top players in big matches. He went through it himself," said Murray.
"So when you have someone like that in your corner, I don't feel bad about those losses.
"I learned much better from, for example, Australia this year compared with the year before, and also Wimbledon this year I learned from much better. I played one of my best tournaments ever at the Olympics, which in the past when I had tough losses I haven't done.
"He has obviously helped me with that. Having someone like him in your corner is always going to help in tough situations. That's when you want them."
The 25-year-old completed his win against Raonic in just two hours without facing a break point.
Raonic was more convincing in his assessment of his personal demolition. "He took me out of the match," admitted the 21-year-old. "At the end, he said, 'Sorry, I got lucky a few times.' I said, 'Don't be sorry, it was simply amazing. Keep it up and you'll do well.'"
Williams sisters out
Nadia Petrova and Maria Kirilenko avenged a pair of stinging London defeats by beating Venus and Serena Williams in the women's doubles.
Petrova and Kirilenko claimed a 6-1, 6-4 victory for their first victory over the American sisters, to reach the quarterfinals.
The Williamses beat the Russians 3-6, 6-3, 9-7 in the second round at the Wimbledon championships. Serena and Venus then returned to London to beat the Russian pair 7-5, 6-4 in the Olympic semifinals.
