Tommy Haas showed he was still capable of springing a surprise at the age of 34 by ending a three-year title drought and beating second seed Roger Federer 7-6, 6-4 in the Halle Open final on Sunday.
The German, who needed a wildcard to play in the event as he is now ranked 87th, had declared himself 'mystified' with his unexpected passage to the final.
He was even more amazed on Sunday after beating a 30-year-old opponent who was the overwhelming favourite to win a sixth title at the Wimbledon warm-up event.
Haas's win also snapped a 10-year losing streak against Federer, with the Swiss having won their last nine meetings dating back to the 2002 Paris Masters.
Haas last captured a title at the same grasscourt venue in 2009.
Just weeks later he enjoyed his most successful run at Wimbledon when he reached the semi-finals and will be hoping Sunday's result will also be a launchpad for another run deep into the tournament.
Federer has already enjoyed a memorable week at the German town in North Rhine-Westphalia after the main pathway up to the tennis stadium was named after him.
The 16-times grand slam champion is unlikely to be too concerned about failing to clear the final hurdle here as he would have fine-tuned his game for Wimbledon during the four matches he has played here.
The Swiss has won this tournament on five previous occasions - from 2003-06 and 2008. He also the 2010 final here to Australian Lleyton Hewitt.
Federer now has a 74-31 mark in career finals, 11-3 on grass. It was his first loss in five finals this year, having won in Rotterdam, Dubai, Indian Wells and Madrid.
