The abbreviated 2020 season was full of the unexpected, both on and off the court, and there were results that shocked fans and players alike. Let's take a look at the Top 10 biggest upsets of 2020.



Setting: Australian Open, third round

Ranking: Wiang, No. 23 vs. Williams, No. 9

Score: 6-4, 6-7 (2), 7-5

Thanks in part to Wang Qiang, the hunt for a 24th title for Serena Williams continues. The 28-year-old, coming into the Australian Open as the 27th seed, stunned the former world No. 1 despite losing the second set. Qiang had some help from Serena, who hit 56 unforced errors compared to the Chinese player's 20.

This win was unexpected since Williams defeated Wiang at the 2019 US Open, 6-1, 6-0. In Melbourne, the 28-year-old stayed calm and composed throughout the match. She could not keep up the momentum, losing to Ons Jabeur in the next round.

This was the first time that Serena had lost before the fourth round in Melbourne since 2006.
