LAUSANNE (AFP) - Stan Wawrinka, who suffered a shock first round exit in Rome last week in his first match in three months, returned to winning ways on Wednesday (May 23) by seeing off Jared Donaldson of the United States 6-3, 6-4 in his Geneva tournament opener.

Wawrinka is building up to the French Open which he won in 2015 but his career has been badly affected by a recent knee injury that required surgery and meant he had only won three matches all year before Wednesday.

The Swiss star, twice a champion in Geneva, only got on to court just after 9pm due to rain at the Swiss venue.

He will face Hungary's world number 60 Marton Fucsovics in Thursday's quarter-finals.
