Sam Querrey knocked off steely Robo-Djoker 5000 in a third-round

Last week, American tennis player Sam Querrey did the unthinkable: He knocked off steely Robo-Djoker 5000 in a third-round match at Wimbledon, snapping the Serbian’s streak of 30 straight Grand Slam match victories.

6 ranked Milos Raonic looming, suddenly the question has become: Is it finally time to get excited about an American men’s tennis player again? The last American victory at the ATP World Tour Finals was in 1999; the last Grand Slam victory came in 2003.

Which brings us to Querrey, 28, who will be playing in his first Grand Slam quarterfinal, and the first for any American man since the 2011 U.S.

2 seed Andy Murray, who had yet to lose a set at Wimbledon heading into his own quarterfinal match against Jo-Wilfried Tsonga, likely awaits in the finals.

His match with Djokovic was unusual, to say the least: It had three separate rain delays, which visibly threw Djokovic off his rhythm, especially against a 6-foot-6 giant who throws haymaker serves.

A big server, he is known for keeping his cool in matches: He flips his racket between points; during the rain delays in his match against Djokovic undisputably the highest stakes of his career he took to playing with golf putters in the locker room.

So, for all the American flag emoji that appeared on Twitter after he upset Djokovic, Querrey probably will not be the one to end U.S.
