LONDON — They sighed when Andy Murray faulted.
They stood and roared when he hit winners.
And when Murray dropped the first two sets of his Wimbledon quarterfinal Wednesday, the 15,000 Centre Court spectators were suddenly so silent that birds could be heard chirping.
By the time his five-set comeback was nearly complete, more than two hours later, the fans were greeting each point that went Murray's way with celebrations of the sort normally reserved for a championship. It's been 77 years since a British man won the country's Grand Slam tennis tournament, and thanks to the second-seeded Murray's 4-6, 3-6, 6-1, 6-4, 7-5 victory over 54th-ranked Fernando Verdasco, the locals still can hold out hope the wait will end Sunday.
First things first, of course. Murray, who is from Scotland, will play in the semifinals at the All England Club for the fifth consecutive year Friday, facing No. 24 Jerzy Janowicz of Poland. The other semifinal is No. 1 Novak Djokovic of Serbia against No. 8 Juan Martin del Potro of Argentina.
There is no doubt who will be the recipient of the most boisterous support.
"Great atmosphere at the end of the match. ... I love it when it's like that. It was extremely noisy," said Murray, who lost last year's Wimbledon final to Roger Federer. "They were right into it, pretty much every single point."
Murray needed to summon some pretty strong tennis, and plenty of grit, for his seventh career victory after facing a two-set deficit. He never panicked — no matter what all of his self-admonishing muttering and gesticulating looked like — and eventually figured out how to handle Verdasco's 130 mph serves and high-risk, high-reward style.
