How well do you know the U.S. Open tennis tournament.

Novak Djokovic has not been tested in a set, let alone a match, at this year's French Open.

Serbia's Novak Djokovic reacts after missing a shot against Sweden's Mikael Ymer in the first round match of the French Open tennis tournament at the Roland Garros stadium in Paris, France, Tuesday, Sept. 29, 2020. “Winning a 6-love first set is the best possible way to start a Grand Slam," he said. With Dominic Thiem, the U.S. Open champion and two-time French Open runner-up, watching from the stands in a black winter coat, Djokovic broke Ymer nine times and ended up with a 32-12 edge in total winners. Others feeling that way on Day 3 at the year’s last Grand Slam tournament included No. Tsitsipas trailed Jaume Munar before advancing 4-6, 2-6, 6-1, 6-4, 6-4, while Rublev knelt on court and covered his face with his hands after turning things around to beat Sam Querrey 6-7 (5), 6-7 (4), 7-5, 6-4, 6-3.
