With the unique format at the WTA Finals, it is all about how you finish rather than how you start, as new champion Agnieszka Radwanska proved in Singapore this week.

The Pole became the first winner of the end-of-season championships for the top eight women to lose two out of three matches in the round-robin phase.

The 26-year-old used her supreme court coverage and superb shot selection to dispatch double Wimbledon champion Petra Kvitova 6-2, 4-6, 6-3 in Sunday's final at the Indoor Stadium to land the biggest title of her career.
