ISTANBUL, Turkey  - Czech teenager Marketa Vondrousova reached her fourth consecutive quarterfinal of the season at the TEB BNP Paribas Istanbul Cup on Thursday with a 6-4, 6-3 win over two-time Grand Slam champion Svetlana Kuznetsova.

The in-form Czech broke the Russian's serve a staggering seven times in the match overall en route to the straight-sets victory, avenging a defeat from their first meeting two years ago, where she was unable to convert three match points at the 2017 US Open.

Vondrousova avoided a repeat of their only previous encounter in emphatic fashion, breaking to 15 to seal the match after seeing Kuznetsova save a match point and break serve to stay alive late in the second set.

In a match largely dominatd by return, Vondrousova was the first of the two players to establish herself in the opening set.

After the pair traded early breaks, Vondrousova won three games in a row to build a 5-2 lead in the opening set, only to see Kuznetsova get one of the breaks back and save a set point to pull closer.

The Czech would make no mistake in her second opportunity to serve out the set with an easy hold, and she carried that momentum on serve early in the second set as well.

The World No.46 dropped just two points on serve and broke Kuznetsova twice en route to building a 4-1 lead in the second set, but the Russian broke to love in the sixth game, and later ground out another break of serve after saving match point in the eighth.

Undaunted by the former World No.2's efforts, Voundrousova calmly moved over the line with the match's 11th overall break of serve, booking herself a place in the last eight opposite Lara Arruabarrena, who upset top seed Carla Suárez Navarro in the first round.
