MELBOURNE, Australia -- Flavia Pennetta's late-career revival continued as she reached her first Australian Open quarterfinal on Sunday with a 6-1, 4-6, 7-5 win over ninth-seeded Angelique Kerber of Germany.
The 28th-seeded Pennetta, who turns 32 next month, has played some of her best tennis since returning last February from a wrist injury that caused her ranking to drop as low as No. 166.
The Italian veteran reached her first Grand Slam semifinal at the U.S. Open last year and has followed that by reaching her first quarterfinal at Melbourne Park in 11 appearances.
"I'm a little old so I'm starting to enjoy [tennis] more," she said. "When you are young you want to win so much."
Pennetta broke Kerber to take a 5-3 lead in the third set but tightened up as she was serving for the match, giving the break right back. She recovered, however, to take a 6-5 lead and then broke Kerber to close out the match.
Kerber was also bidding for her first quarterfinal at the Australian Open. She hasn't been past the fourth round of a Grand Slam since reaching the Wimbledon semifinals in 2012.
Pennetta next plays two-time finalist Li Na of China, who beat Ekaterina Makarova of Russia.
