Sam Querrey of the United States celebrates after winning the fourth set of his Men's Singles Quarterfinal Match against Britain's Andy Murray on day nine at the Wimbledon Tennis Championships in London Wednesday, July 12, 2017.

LONDON — Limping between points and fading down the stretch, defending champion Andy Murray was stunned by 24th-seeded Sam Querrey of the U.S. 3-6, 6-4, 6-7 (4), 6-1, 6-1 in the Wimbledon quarterfinals Wednesday.

The No. 1-seeded Murray came into the tournament dealing with a sore left hip and it clearly impeded him at Centre Court. He grimaced as he stumbled or landed awkwardly while attempting shots.

Querrey took full advantage to reach the first Grand Slam semifinal of his career — and the first for any American man anywhere since Andy Roddick was the runner-up at Wimbledon in 2009.

Murray is normally a terrific returner, but Querrey hit 27 aces, including on six of the last nine points he served to finish with a flourish. Querrey was impeccable for portions of the match, finishing with 70 winners and only 30 unforced errors.

From 1-all in the fourth, Querrey grabbed eight games in a row to take that set and lead 3-0 in the last.

It is the second year in a row that the 29-year-old Californian upset the defending champion and top-seeded man at the All England Club. In 2016, he beat Novak Djokovic in the third round en route to the only major quarterfinal of Querrey's career before Wednesday.

Querrey is the lowest-ranked player to ever beat two-time Wimbledon champion Murray in his 12 appearances at the grass-court Grand Slam tournament.
