Round of Upsets

In the men's draw, the most promising young players along with a seasoned veteran, are out before they were even able to challenge the Big 3 of Nadal, Federer and Djokovic. As for the women's draw, four Grand Slam winners, including three Wimbledon champs, exited the grounds empty handed.

Venus Williams

This might have been the most inspiring upset of them all. The seven-time Grand Slam champion and five-time Wimbledon champ lost in straight sets to 15-year-old Cori "Coco" Gauff. When Gauff was born in 2004, Williams has already won four of seven major titles. Gauff grew up with the Williams sisters as her idols, and now she beat one of them.

Naomi Osaka

The past year for Osaka can only be described in comparison to the big drop on the rollercoaster: everything is going up, and when you get to the top, it's a fast downfall. The No. 2 seed won back-to-back Slams at the U.S. Open and Australian Open, but the next two? Eliminated in the first round. For the second time in the last two weeks Yulia Putintseva swept Osaka in her biggest win in a major. Osaka tallied 38 unforced errors, while the unranked Putintseva had only seven.

Alexander Zverev

Czech qualifier, Jiri Vesely, defeated the sixth seed in four sets, 4-6, 6-3, 6-3, 7-5. Vesley, a dangerous lefty, entered Wimbledon ranked No. 124, and hit 80 percent of his first serves. Zverev couldn't find a way to break and won only one-of-seven break points. In his post-match press conference, Zverev admitted to being at a point of low confidence right now, which showed in his not being clutch in crucial points of the match.

Dominic Thiem

Sam Querrey was a semifinalist in 2017 and knocked out the No. 5 seed Thiem in an impressive first round performance, 6-7 (4), 7-6 (1), 6-3, 6-0. Querrey hit 90 percent of first serves and was perfect in break points. Thiem was coming off a French Open final, taking a set off the 12-time champion Rafa Nadal.

Stefanos Tsitsipas

Thomas Fabbiano had never, before Monday, taken a set off a Top 20 player. He defeated the seventh seed 6-4, 3-6, 6-4, 7-6 (10), 6-3. Last year, Tsitsipas took only 91 minutes and seven lost games to eliminate the Italian from the third round of Wimbledon. Even though Fabbiano let two match-points slip away in the fourth set tiebreaker, he was able to pull it back together in the fifth to defeat the tournament contender.

Stan Wawrinka

Three-time major champion Stan Wawrinka was ousted by unseeded Reilly Opelka of the United States 7-5, 3-6, 4-6, 6-4, 8-6 in the second round. The 63rd-ranked Opelka, who is making his debut at Wimbledon, earned the only service break of the fifth set in the last game, helped by four groundstroke errors from Wawrinka, who was seeded 22nd.
