Liudmila Samsonova and Xiyu Wang cause upsets in the final eight at the Citi Open.

At the Citi Open, the two top seeds who were still in the draw lost in the quarterfinals on Friday. While Xiyu Wang defeated fourth-seeded Azarenka, Liudmila Samsonova upset second-seeded Emma Raducanu. Azarenka played Tereza Martincova on Friday after the second round match was postponed due to rain.

Azarenka triumphed 7-6(7), 6-2 after 210 minutes. However, the former world number one was unable to make much of an impact on lucky loser Wang, who won 6-3, 6-1 in an hour and 20 minutes. Wang defeated Azarenka by a margin of 72 percent to 51 percent in first-serve points and by a margin of 41 percent to 27 percent in second-serve points.

Additionally, she converted six break points on Azarenka’s serve while saving three of the five break points she encountered. Samsonova will compete against Wang in the semifinals.

Kaia Kanepi is still competing at Citi Open.

Samsonova defeated the Briton 7-6(6), 6-1, in an hour and 46 minutes.

On Raducanu’s serve, Samsonova won 79 percent of her points with her first serve and converted five of her seven break points. She earned 78 points overall during the game, 11 more than the other player’s 67. In Washington, DC, Daria Saville finished Rebecca Marino’s performance.

The Australian won in one hour and 19 minutes, 6-1, 7-5. Six of the seven break points she encountered were saved, and five of the six break point opportunities she received were successful. For the game, Saville scored 65 points to the Canadian’s 50.

Saville will face Kaia Kanepi, the sixth seed, in the Citi Open final as she attempts to make her first final in over five years. The Estonian’s match with Anna Kalinskaya lasted the longest of the day, clocking in at two hours and 33 minutes.
