Serena Williams claimed a fourth successive win over sister Venus to triumph at the Sony Ericsson Championships in Doha yesterday. Serena, who was guaranteed to end the season as world No 1, completed her fifth straight win of the prestigious end-of-season tournament, easing to a 6-2, 7-5 victory.
She wasted little time taking the first set but had to dig deeper in the second before winning the tie-break to go 13-10 up on defending champion Venus in professional meetings between the world-beating American siblings.
Serena insisted afterwards her near faultless campaign had far exceeded her expectations as she collected a second Tour Championships title. "I didn't expect to come here and win," she admitted.
