Williams Sisters set up third round clash at US OPEN

                                              

 Serena Williams set up a third-round encounter with sister Venus as she defeated Germany’s Carina Witthoeft in emphatic fashion at the US Open.

The two former world No 1s will meet for the 30th time in their illustrious careers after the 23-time Grand Slam champion Serena won 6-2 6-2 in the opening match of the night session on the Arthur Ashe Stadium.

Six-time champion Serena, who missed last year's edition to give birth to her first child, impressed as she mixed 30 winners with 13 aces to progress in 67 minutes against the world No 101.

               

Venus had earlier defeated Italy's Camila Giorgi, who pushed Serena to three sets at Wimbledon last month, 6-4 7-5 to maintain her hopes of a third US Open singles title.

The Williams sisters have not met at such an early stage of a Grand Slam since their first professional meeting at the 2nd round of the 1998 Australian Open.
