INDIAN WELLS, CA, USA -- Czech lefty Marketa Vondrousova notched a Top 20 win at the BNP Paribas Open on Friday when she eliminated 2018 finalist and No.14 seed Daria Kasatkina of Russia, 6-2, 6-1 in the second round.

19-year-old Vondrousova, who reached her second career WTA singles final at Budapest earlier this year, needed just 70 minutes to dispatch the World No.14. The powerful Czech faced only one break point in the entire match, which she saved, and won 75 percent of points when she got her first serve in play.

Kasatkina only won half of her first-service points, and less than that on her second serve as she fired five double faults in the match. The Russian, who finished 2018 ranked World No.10, will see her ranking tumble out of the Top 20 after failing to defend her runner-up points from last year, where she lost to Naomi Osaka in the title match. Kasatkina is just 1-6 on the season thus far.

World No.61 Vondrousova sets up a third-round matchup with No.22 seed Jelena Ostapenko of Latvia. Ostapenko, the 2017 French Open champion, cruised past Zhang Shuai of China, 6-2, 6-1 in one hour and nine minutes on Friday. Ostapenko won a solid 62 percent of points on her second serve, while Zhang blasted eight double faults in the tilt.

Another noteworthy head-to-head pattern was continued on Friday when American wild card Jennifer Brady beat No.19 seed Caroline Garcia of France, 6-3, 3-6, 6-0. Garcia won their first two meetings, but in 2019, the rivalry is all Brady's, as the American has beaten the Frenchwoman all three times they have played this season.

Brady rolled through the deciding set, winning eight of her nine first-service points and never facing a break point during that timeframe. World No.83 Brady moves into the third round, where she will take on No.12 seed Ashleigh Barty of Australia, who beat Tatjana Maria of Germany, 6-4, 6-4, in 88 minutes.

Johanna Konta also had an swift win over a seeded player, as the Brit eased past crafty No.27 seed Hsieh Su-wei of Chinese Taipei, 6-0, 6-2, in 70 minutes. A steely Konta faced a whopping 12 break points in her match, and saved them all.

In other matches, No.7 seed Kiki Bertens of the Netherlands eased past Poland's Magda Linette, 6-4, 6-1, and No.16 seed Elise Mertens of Belgium came back from a break down in the first set to take out American teenager Amanda Anisimova, 6-4, 6-2. No.18 seed Wang Qiang of China also had a straight-set win, 7-6(5), 6-2, over American Bernarda Pera.

But other seeds were not so lucky late in the day. Australia's Daria Gavrilova ousted No.29 seed Mihaela Buzarnescu of Romania, 6-2, 6-2, and Ukrainian qualifier Kateryna Kozlova outlasted No.31 seed Aliaksandra Sasnovich of Belarus, 6-4, 2-6, 6-0.

Finally, up-and-coming Canadian teenager Bianca Andreescu continued her great run of form with a 6-2, 6-2 upset of No.32 seed Dominika Cibulkova of Slovakia. Andreescu was never broken in the 83-minute match, as she improved her 2019 win-loss record to a whopping 23-3.
