Serena Williams says she "did not choke" after missing four match points as Czech seventh seed Karolina Pliskova won the final six games to win a dramatic Australian Open quarter-final.

The 37-year-old American, going for a record-equalling 24th Grand Slam singles title, led 5-1 in the decider but lost 6-4 4-6 7-5 in Melbourne.

"I think she just played lights out on match points," Williams said. "I took my chances," said Pliskova who won on her third match point.
