Wawrinka reaches last eight in India

Defending champion Stanislas Wawrinka progressed through to the quarter-finals of the Chennai Open today, but needed to come back from a set down to do so.

The Swiss, who also finished runner-up in 2010, found himself trailing to Frenchman Edouard Roger-Vasselin before recovering to claim a 3-6 6-3 7-5 win.
