Tennis legend Martina Navratilova has stepped up her twin-pronged assault on a new record of 21 Wimbledon titles.
The evergreen 48-year-old, who won the last of her nine singles titles 15 years ago, is through to the semi-finals of the women's doubles and the last eight of the mixed doubles.
Navratilova began on Court Two, where she and Anna-Lena Groenefeld, of Germany, beat Vera Douchevina and Shahar Peer 7-6 6-4 in the quarter-finals of the women's doubles.
And five hours later she combined with Mike Bryan, who was still in nappies when Navratilova lifted her first Wimbledon title in 1978, to beat fellow Americans Travis Parrott and Amy Frazier 7-5 6-7 6-4 in the third round of the mixed doubles.
Court One quickly refilled after the finish of the second men's quarter-final as fans flocked to witness Navratilova's attempt to reclaim the title she won with Leander Paes two years ago to equal Billie Jean King's record of 20 titles.
She was the first player to drop her serve but otherwise rolled back the years in impressive fashion.
Parrott and Frazier had set point in the ninth game but Navratilova and Bryan, the fifth seeds, fought back from 3-5 to take the first set 7-5 after both their opponents double-faulted on break point.
Bryan also dropped his serve at the start of the second set but, urged on by the partisan crowd, they broke back to force a tie-break.
The 27-year-old Bryan was then given an official warning for slamming the ball out of court after missing a backhand volley at the net and Parrott and Frazier took the tie-break 7-4 to level the match. It was only a temporary setback, however, as Navratilova and Bryan clinched the final set.
