World No.1 Serena Williams cruised into the Madrid Open quarterfinals as she dismantled 13th seed Maria Kirilenko 6-3, 6-1 in just an hour and four minutes on Thursday.
The American, who is yet to be beaten in eight matches on clay this season, held a perfect 6-0 head-to-head record with the Russian before the match and never looked in danger of extending that streak to seven out of seven.
World No.2 Maria Sharapova also continued her stroll into the quarterfinals without even losing a set so far as she over came Sabine Lisicki 6-2, 7-5.
The Russian broke the Lisicki serve four times to prevail in a disjointed opening set.
Serve was more dominant in the second set with both players exchanging just the one break early on before Sharapova secured a crucial second break at 5-5 and served it out to take her place in the last eight.
