The German pair of Sabine Lisicki and Christopher Kas have advanced to the last four of the Olympic mixed doubles after edging Roberta Vinci and Daniele Bracciali of Italy in a super tie-break.
It was the Italian pair who took the opening set 6-4 after both pairs lost their serve early on at Wimbledon's No. 2 Court.
There were no breaks of serve in the second set and the Germans stayed in the match by taking the tie-break 7-2 to send the game into a deciding 'super' tie-break, where the first to 10 points wins the match.
Neither duo produced a strong service performance in the breaker but it was the Germans who won through 10-7 to seal their place in the last four.
They will face either Laura Robson and Andy Murray of Great Britain or Australia's Sam Stosur and Lleyton Hewitt.
