LONDON: Serena Williams turned up the heat on sister Venus as the two-time champion swept into the Wimbledon quarter-finals with a 6-3, 6-1 victory over Daniela Hantuchova on Monday.
As temperatures soared on the hottest day of the year in England, second seed Serena showed she has no intention of letting Venus have it all her own way at the All England Club by brushing aside unseeded Slovakian Hantuchova in 56 minutes.
Serena and Venus have already contested three Wimbledon finals, as well as making a combined 11 appearances in the final.
Venus, who also made it to the last eight thanks to Ana Ivanovic's withdrawal midway through their fourth round match, beat Serena in the final here 12 months ago and the Americans remain on course for another sister act in this year's showpiece.
Hantuchova never had a chance of halting Serena's charge towards the final.
The former world number five had almost lost her voice after suffering from flu since arriving at Wimbledon and she might have better off staying on her sick bed.
Serena was again shunted out to Court Two but she didn't seem bothered by the unglamourous surroundings of Wimbledon's smaller show court.
The Australian Open champion was able to over-power Hantuchova in the first set and then broke twice at the start of the second set to cruise through.
