Japan's Kei Nishikori, who did not drop a set all week, easily defeated Feliciano Lopez 6-2, 6-3 in the final of the US Indoor Tennis Championships, claiming his third career ATP Tour title. The 23-year-old Nishikori needed just 67 minutes to earn his second title in four months as he managed to break unseeded Lopez's serve four times on Sunday. "I'm very happy with the way I played today," said Nishikori.
