Drawing: Stan the man (Stanislas Wawrinka)

Stanislas WawrinkaWorld number 4 Stan Wawrinka narrowly lost a tense semi final against compatriot Roger Federer at the ATP World Tour Finals in London on Saturday evening.

Given the latter’s withdrawal from the final, due to a back injury sustained in the long match, many Swiss supporters may have wish a different result in hindsight.

Stan made his first Grand Slam breakthrough in January this year, beating Rafael Nadal in the final of the Australian Open. He also won a gold medal with Roger at the 2008 Summer Olympics in Beijing.

Both men now head to Lille to contest the Davis Cup Final against France this weekend.
