Top-ranked Novak Djokovic was stunned in the third round at Wimbledon by 28th-seeded Sam Querrey of the United States on Saturday. Querrey pulled off the shocker 7-6 (6), 6-1, 3-6, 7-6 (5).

Djokovic began the day down two sets to none after Querrey took a commanding lead before play was suspended by rain on Friday. Djokovic won the third set but not before the rains arrived again and forced a nearly two-hour delay. The weather also was a factor late in the fourth set with Djokovic about to serve down 6-5. When the players returned to the court, Querrey stormed back and won the match on a tiebreaker.

Querrey entered the tournamant ranked 41st in the world. He had been 1-8 against Djokovic in his career and never has advanced past the fourth round in any major.
