South Africa’s Kevin Anderson has advanced the fourth round of the BNP Paribas Open tennis tournament in Indian Wells, California.
The seventh seed beat Argentine Nicholas Kicker 7-6, 7-6 to join world number one, Roger Federer, in the last 16.
Federer needed less than an hour to dispatch Serbia’s Filip Krajinovic in straight sets.
Weather delays in Indian Wells saw Federer playing for the third straight day, but the 2018 Australian Open champion showed no sign of fatigue as he thrashed the Serb 6-2 and 6-1.
It was the pair’s first ever meeting and Krajinovic simply had no answer for the Swiss’ accurate serve or relentless returns.
With rivals Rafael Nadal, Stan Wawrinka and Andy Murray electing not to enter the tournament, and Novak Djokovic and Kei Nishikori both out.
The top seed looks set to win a record sixth title here with his next match on Wednesday against Frenchman Jeremy Chardy.
