In a result that sent shockwaves throughout the tennis world, Sam Querrey defeated World no. 1 Novak Djokovic 7-6, 6-1, 3-6, 7-6.

It was a match that unfolded over two days and took nearly 3 hours of court time, but it turned out to be the perfect storm for the American. Querrey played poised and with a confidence unseen in quite some time, while Djokovic appeared to be a mere mortal.

The Serb entered the match on the heels of a 30 straight grand slam match streak, having won the last four majors. Many opined that he might achieve a calendar year grand slam in 2016 which would have been the first since Rod Laver accomplished the feat in 1969. He entered Wimbledon after finally adding a Roland Garros title to his trophy case and was clearly in the midst of one of the most dominant periods of tennis the men’s game has seen. Yet, it was the American who came up with the big points during the match.

On Friday, Djokovic showed signs that perhaps he was not at his best, particularly in a second set where he appeared flat and not at his usual engaged standard. It was thought that he caught a break as play was suspended.

As play resumed on Saturday, he appeared to have regrouped, taking the first four games of a third set that was interrupted by rain. Cutting the set deficit to 1-2, he worked himself back into the match and captured the momentum. And in the fourth set, Djokovic put himself into great positions against the big Querrey serve. But the 28-year old would fend off the top-seed who was only able to capitalize on 1 out of 12 service break opportunities.

And as play advanced to a tiebreak, the Serb played a handful of uncharacteristically, loose groundstrokes. The errors set up two match points for Querrey and while Djokovic saved one, the Californian would close it out at 7-5.

Querrey took his shots during the match, striking 56 winners and his serve was a massive weapon, generating 31 aces. Meanwhile, Djokovic struck 31 unforced errors, many coming at key points of the match.

It was the match of Querrey’s career, who was thrilled afterward, “It's incredible, especially to do it here at Wimbledon. I'm so ecstatic right now and so happy,” he said. “I played the break points really well. Got a couple of loose errors and that was it.”

He anticipated a run by Djokovic stating, “Today he came out and got the first four games. He's so amazing, he's on the way to being possibly the best ever so you know he's mentally tough and going to come back.”

Meanwhile, Djokovic credited Querrey but hinted that he wasn’t at peak health, “Sam played a great match. His game was brutal and I was overpowered today,” he said. He continued, stating that he “wasn't 100 percent healthy. But this is not the place or time to talk about it.” He immediately announced that he would bypass the upcoming Davis Cup tie against Great Britain.
