A year after pulling off a massive upset at Wimbledon, the 6-foot-6 Californian did it again Wednesday, beating defending champion and No. 1-ranked Andy Murray in five sets 3-6, 6-4, 6-7 (4), 6-1, 6-1 in a quarterfinal match.
Murray had arrived at the All England Club feeling the effects of his right hip problem.
Querrey is headed in the opposite direction: Merely 4-10 in fifth sets for his career until last week, he has won each of his last three matches by going the distance: against 12th-seeded Jo-Wilfried Tsonga in the third round, Kevin Anderson in the fourth, and now Murray.
"I beg your pardon?", the journalist responded, not appearing to understand what the sportsman said.
"I'm still in a little bit of shock myself", Querrey said after the match. There's a bit more wear and tear there.
However, the injury may have flared up during his match with Querrey as he was visibly limping in the final stages of the match, as was clear in a tweet from BBC commentator David Law. You're trying to get yourself in the best shape possible for this tournament, and I did that.
He might well have won the second set, too, but, after breaking for 4-3, lost his way and the last three games. "I wasn't that far away". But I nearly found a way to get into the semis.
He smiled and waved to them when it was finally over, and Murray walked off the court, still doing his best to disguise his uncomfortable gait.
"Querrey has had some long matches but he has a day off tomorrow to ensure an easy day and then get ready for Friday". "If it means taking a few weeks' rest, then so be it", explained Murray.
Querrey's shocked the tennis world before; a year ago, he beat No. 1 at the time Novak Djokovic in the third round in the Wimbledon third round (but was beat in the quarters).
He admitted that losing top spot wouldn't be a surprise as his form has fallen below his high standards this year.
Serving at 4-2 up, Murray refused to chase down an routine lob that landed within his normal reach.
Hewitt said it was extraordinary to think that when 35-year-old Federer took over from him in 2003, he would still be competing for the Wimbledon title 14 years later - and looking none the worse for it. I'm sure moving forward I'll be able to get through it. "I'm just thrilled right now", Querrey said afterwards.
"And Cilic, yes he will push him more, but I just feel Andy's mentality, being on Centre Court, and with his experience - Andy never lets any opportunities go".
