MELBOURNE - World number one Serena Williams Friday said she could end her 13-year boycott of the Indian Wells tournament after being inspired by Nelson Mandela. The American 32-year-old and her sister Venus have not played the event in the California desert since being booed in 2001. It followed Venus pulling out of their semi-final just minutes before they were due to play, citing injury, handing Serena a walkover into the final. The capacity crowd was livid and made their feelings clear during the final against Kim Clijsters, booing Venus and her father Richard as they entered the stadium and Serena throughout the match. There were even claims of racist taunts. Serena met South African anti-apartheid hero Mandela, who died in December, and recently watched a film about his life. –AFP
