Kevin Anderson handed Japan's Kei Nishikori a humiliating 6-0, 6-1 thrashing at the ATP Finals as the South African moved to the brink of a semi-final berth on Tuesday. Anderson won the first 11 games and needed only 64 minutes to demolish the woeful Nishikori in a remarkably one-sided group stage clash at London's O2 Arena.

Having also won his opening match against Dominic Thiem in his debut at the prestigious season-ending event, Anderson is close to becoming the first African to qualify for the last four at the ATP Finals. The 32-year-old's place will be secure if Thiem beats Roger Federer, or if Federer defeats Thiem in three sets later on Tuesday. It was a landmark moment for Wimbledon finalist Anderson, who has set a new career-high of 47 victories in a calender year.
