Serena's day of reckoning in Singapore
Serena Williams underlined her dominance of women's tennis by winning the season-ending WTA Tour Finals for the third year in a row yesterday. She turned the tables on Simona Halep - who had upset the American in the group stage - by trouncing the Romanian 6-3, 6-0 in the final at the Singapore Indoor Stadium. Williams has now ended the year as world No. 1 for the fourth time.
