The top three seeds all made it through to the quarter-finals of the Miami Open.
Angelique Kerber barely broke sweat as she dropped just four games in a 6-2 6-2 win over qualifier Risa Ozaki, while second seed Karolina Pliskova did not have to work much harder to get past her fellow Czech Barbora Strycova as she came out a 6-1 6-4 winner.
The same cannot be said for third seed Simona Halep, who saved a match point before eventually coming back to beat Sam Stosur 4-6 7-5 6-2.
The Romanian was staring down the barrel at a set and 5-2 down before she reeled off 11 of the next 13 games to book her last-eight spot.
However, fourth seed Dominika Cibulkova was ousted as she fell in straight sets to Lucie Safarova, with the Czech, who specialises in doubles, winning 7-5 (7/5) 6-1.
Sixth seed Gabrine Muguruza is also out as illness caused her to retire during her clash with Caroline Wozniacki, with the Dane having just won the first set.
Seventh seed Svetlana Kuznetsova was another top 10 seed to fall as she was soundly beaten by Venus Williams, with the veteran claiming a 6-3 7-6 (7/4) success.
Johanna Konta cruised into the quarter-finals for a second successive year after seeing off Lara Arruabarrena in straight sets, winning 7-5 6-1, while Australian Open semi-finalist Mirjana Lucic-Baroni beat Bethanie Mattek-Sands 7-5 6-4.
