LONDON, Nov. 13 (Xinhua) -- Kevin Anderson blasted his way to a 6-0, 6-1 win over Japan's Kai Nishikori to claim his second win of the ATP Finals on Tuesday.

The South African, who defeated Dominic Thiem in his opening match on Sunday in the Leyton Hewitt group, needed less than an hour and five minutes to claim a hugely one-sided win.

While Anderson was once again on the top of his game, Nishikori was a shadow of the player who beat Roger Federer 7-6(4), 6-3 on Sunday and had no answer to Anderson's powerful serve.

Prior to the match, Anderson had promised to donate $100 US dollars for every ace he hit to firefighters combatting the current wildfires around Los Angeles and after hitting 10 aces in the match, he raised a total of $1,000 dollars.
