Stanislas Wawrinka has bowed out in round one of the Swiss Indoors event after losing to Frenchman Edouard Roger-Vasselin 6-4, 6-3 on Tuesday.

The 28-year-old has failed to surpass the first-round of his home event on four other occasions in his career, but this exit carries the additional setback of seriously denting his chances of qualifying for the ATP World Tour Finals in London next month.

Wawrinka played nowhere near his best tennis against Roger-Vasselin and sealed his early departure from the tournament within barely an hour, having lost his serve once in both sets.

Although the Swiss is currently eligible to play in the London event, the world number eight is closely pursued in the mens rankings by Frenchmen Richard Gasquet and Jo-Wilfried Tsonga.

It will take a miraculous effort from Wawrinka to book his place in the prestigious tournament; requiring a career-best run in next week's qualifying series in Paris to secure his hopes of making the cut.
