Angelique Kerber survived some nervous moments before fending off American teenager Madison Keys in the third round of the Australian Open, then got to blow out the candles on a cake to celebrate her 25th birthday.

Fifth-seeded Kerber won 6-2, 7-5 on Friday to move into the fourth round, further than she's gone in six trips to the Australian Open.

Local organizers brought Kerber a cake onto the court immediately after the match and the crowd at Rod Laver Arena sang "Happy Birthday." She blew out the candles and said thank you to the crowd and to 17-year-old Keys.

"Madison is a great young player and it was very tough," said Kerber, a semifinalist last year at Wimbledon. "So happy I won today on my birthday!"

Kerber will next play No. 19 Ekaterina Makarova of Russia, who advanced after a tough 6-7 (4), 6-3, 6-4 win over 2007 Wimbledon finalist Marion Bartoli.
