The youngest player in the tournament, Coco Gauff, at just 15-years old upset her hero, Venus Williams, two days ago. Her unprescedented win was followed up with a victory over Magdalena Rybarikova today. Rybarikova is not highly ranked at just 139 but she was a semifinalist at Wimbledon in 2017. Gauff once again won in straight sets 6-3, 6-3.

Her victories at Wimbledon are shocking to most people. Gauff was a wildcard into the tournament and she is ranked outside the top 300 at 312. On paper Gauff should not be going to the third round, but if you ask Gauff if she’s surprised she responds confidently with, “I think I can beat anyone.”

Another American upset was with Danielle Collins defeating Anastasija Sevastova, the 12 seed. Collins had to go all three sets after dropping the first set. The match would end with a score of 4-6, 6-4, 6-3.

The two seeded Americans on the day would not be so fortunate as their compatriots. 27th seeded, Sofia Kenin, was taken down by Dayana Yastremska. The match went a full three sets, but Yastremska took the final set with a commanding 6-3 win.

The most surprising USA upset was when Madison Keys, seeded 17th, lost to Polona Hercog in straight sets. Wimbledon has always been a struggle for Keys, who has never made it past the quarterfinals. She has made it to at least the semifinals in all of the other Grand Slams.

Top seeded players Karolina Pliskova, Simona Halep and Elina Svitolina all moved on to the third round and will play on Friday July 5.

The main matches tomorrow will be with the top seed Ashleigh Barty facing Alison Van Uytyan and defending Wimbledon Champion Angelique Kerber against Lauren Davis. Coverage begins at 6 am ET tomorrow on the ESPN networks.
