A massive traffic jam caused top seed and world number one, Serena Williams, to borrow a bicycle from her hotel to cycle to the Miami Open on Saturday, an unusual occurrence which she thought was cool, but it may have had an effect on her game, as she started slowly against the Japanese number one, Ayumi Morita. Morita led 3-0 in the first set before Williams changed gears and took the next six games for a 6-3 set. She allowed Morita only three games in the second set with a fierce display of power serving, including seven aces to move into the fourth round where she will take on 13th seeded Dominika Cibulkova.
4th seed Agnieszka Radwanska had a real battle on her hands in her match against 49th ranked Slovak, Magdalena Rybarikova. In the first set the two went toe to toe to a tie breaker which Radwanska eventually won 7-5, but she lost the second set easily at 6-2 before tuning up her game another notch to take the decider 6-3 after two hours and twenty three minutes on court. Her next opponent will be Sloane Stephens.
Na Li, the Chinese 5th seed, took on the American 25th seed, Varvara Lepchenko. Li looked to be winning easily when she went 6-2 4-1 up, but the American then won three games in a row to level before Li took the next two games to take the set 6-4. She will meet Garbine Muguruza in the fourth round.
