Roger Federer's unhappy tennis season continues - the Swiss great has lost to Argentina's Juan Martin del Potro in the final of the Basel Open for the second year running.
The Swiss played some of his best tennis this year but it was still not enough to stop him from being on the receiving end of a 7-6 2-6 6-4 defeat against the powerful Argentine and his 220 kilometres per hour serve.
To add to his woes, victory would have guaranteed Federer a place in the season-ending World Tour Finals but his hopes of qualifying for the tournament he has won a record six times will now be decided at next week's Paris Masters.
It's Del Potro's fourth ATP title of the season after wins in Tokyo, Washington and Rotterdam.
Federer, who won his last grand slam title at Wimbledon in 2012 before claiming a silver medal at the London Olympics, has failed to reach the final of a major tournament this season for the first time since 2002.
His only tournament success was at the low-key Halle event and he was beaten in the final at Rome.
