US OPEN: World No. 17 Maria Sakkari defeats Katerina Siniakova

World No.17 seed Maria Sakkari's rivalry with Katerina Siniakova completed a Grand Slam full set, with the Greek winning 6-4, 6-2 to level the head-to-head at two apiece.

The pair have now played four times, once at each Grand Slam. Siniakova's victories both came in three wildly fluctuating sets, in the first round of the 2018 Australian Open and second round of Roland Garros 2019. When Sakkari wins, the contests are more straightforward: today's result joins her 6-3, 6-4 scoreline in the first round of Wimbledon 2017.

Two-time Wimbledon champion Kvitova will play 17th seed Maria Sakkari in the third round after
