Serena Williams will face sister Venus Williams at the US Open quarterfinals after she brought down Severine Bremond's run to a halt with a 6-2, 6-2 victory.
Serena and Venus have met 16 times previously with both winning eight matches, but this will be the first time they have met in the quarter-finals of a Grand Slam tournament.
Venus Williams, who eliminated Polish Agnieszka Radwanska 6-1, 6-3 on Monday, said life on the court would be easier if she didn't have a superstar sister.
In the other women's fourth-round matches Monday, Russian sixth seed Dinara Safina beat Anna-Lena Groenefeld 7-5, 6-0 and Flavia Pennetta of Italy trounced France's Amelie Mauresmo 6-3, 6-0.
Wednesday's US Open quarterfinal match will be a repeat of this year's Wimbledon final, which Venus won 7-5, 6-4.
