Federer wins 2nd round-robin match at ATP Finals

LONDON (AP) Roger Federer made the most of Kei Nishikori's erratic play Tuesday to secure a 6-3, 6-2 victory and move closer to a semifinal spot at the ATP Finals.

Federer, the most successful player at the year-end tournament with six wins, will progress from Group B if Milos Raonic defeats Andy Murray later Tuesday. The 17-Grand Slam champion will also advance if Murray wins in three sets.

Nishikori made it easy on Federer as he struggled with consistency throughout. The U.S. Open finalist showed his vast array of shots with some superb backhand winners but made too many mistakes and struggled with his serve.

Federer broke for a 3-1 lead in the second set and then held before Nishikori called for a medical timeout and dropped his serve twice.
