Enjoy a look back at the biggest upsets of the season, starting at No. 10 and counting all the way down to the top stunner of the year.

One of the major storylines in the women’s game the past few years has been the depth on display, where it appears that every tournament is up for grabs.

Much to the chagrin of the WTA’s Top 10, that idea was proven as fact at this year’s Wimbledon.

In a first for the Open Era, no one in that elite group made it to the quarterfinals. Not 2017 US Open champ Sloane Stephens, who reached the French Open final only a few weeks earlier, but fell in the first round. Nor did 2018 major winners Simona Halep or Caroline Wozniacki, as the top two seeds fell in the third and second rounds, respectively.

Also falling in the second round was the defending champion, Garbine Muguruza, the earliest defeat for a returning titlist in 24 years.

Venus Williams, the five-time winner and 2017 runner-up, lost in the third round, as did her countrywoman Madison Keys. The only member of the top 10 to get a glimpse of the second week was the seventh seed Karolina Pliskova, who advanced to the round of 16.

Usually when a less-heralded player pulls off a big upset, it’s hard to replicate the intensity required to pull off such a feat. At Wimbledon this year, however, the letdowns were few and far between.

In the end, two Grand Slam champions battled it out for the title with Angelique Kerber defeating Serena Williams, gaining a measure of revenge for the 2016 final. Those two former world No. 1s were outside of the top 10 entering the tournament, which, after all the upsets, proved to be the safest place in the draw.
