Defending champions Martina Hingis and Sania Mirza are through to the quarter-finals of the Ladies' Doubles after dropping just a single game in their third-round match on Monday.
The top seeds swept past American Christina McHale and Latvia's Jelena Ostapenko 6-1, 6-0 in just 46 minutes.
Hingis and Mirza, who have won three of the last four Grand Slam titles, have won each of their first three matches in straight sets for the loss of just 12 games.
Next, they will meet the winner of the third-round encounter between Johanna Konta and Maria Sanchez, and fifth seeds Timea Babos of Hungary and Yaroslava Shvedova of Kazakhstan.
Britain's Konta set aside the disappointment of a second-round exit in the singles draw to partner American Sanchez to a 6-4, 6-1 victory over Australian Anastasia Rodionova and her Croatian partner Darija Jurak on Monday.
A closely fought first set saw Konta and Sanchez race to a 3-1 lead before Rodionova and Jurak clawed their way back to level the set at 4-4.
Konta and Sanchez went 5-4 up and crept to 15-30 in the decisive 10th game. An untimely double fault from Rodionova handed the American and Brit two set points and they managed to convert the second.
Luck also ran out for Britain's Naomi Broady and Heather Watson, who were downed by Germany's Julia Goerges and her Czech partner Karolina Pliskova on Court 14.
The British duo lost the opening 66 minute set 7-5 in the tie-break before levelling the match at one set apiece, snatching the second set tie-break 7-0.
Goerges and Pliskova crept ahead in the third set and ran out 7-6(5), 6-7(0), 6-3 winners in 2 hours, 23 minutes.
