ATP holds minute's silence for victims of Paris attacks

LONDON (AP) Novak Djokovic stretched his winning streak to 15 straight at the ATP finals by beating Kei Nishikori 6-1, 6-1 Sunday.

The top-ranked Serb has not lost at the season-ending tournament at the O2 Arena since 2011. He has won three straight titles since then.

Before the match, the ATP held a minute's silence for the victims of the Paris attacks. The Islamic State group claimed responsibility for Friday's attacks on the Stade de France, a concert hall and Paris cafes that left 129 people dead and more than 350 wounded, 99 of them seriously.
