Croatia's Donna Vekic earned her second Top 10 win of the season with a 6-7(1), 6-3, 6-4 upset of No.2 seed Elena Rybakina in the second round of the German Open, here on Wednesday.

In 2 hours and 14 minutes, World No. 23 Vekic ended the reigning Wimbledon champion's nine-match unbeaten run, as well as her eight-match winning streak on grass. But the Croatian is a capable grass-courter herself, and she is now through to her sixth career WTA Tour quarterfinal on the surface.
