• World No 3 beats Georgian 6-1, 6-4 to reach third round• Pliskova’s serve hit a peak of 116mphKarolina Pliskova – the better of the two Czech sisters – always gives the impression she is about to make a major statement in her sport, yet too often fails to deliver. Still, the world No 3 has cruised into the third round of the 2019
US Open, the first to get there because of the rain delays on Wednesday, and she looks in the mood to go further.
Pliskova took 66 minutes to beat the Georgian qualifier Mariam Bolkvadze 6-1, 6-4 and said courtside: “I’m for sure happy that my serve was better than in the first match,” referring to her error-strewn struggle to overcome her compatriot Tereza Martincova in two nerve-jangling tie-breaks.
