LONDON — 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 while Andy Murray posted his first victory to stay in contention at the elite tournament. Federer, the most successful player at the year-end championship with six wins, would have progressed if Milos Raonic had defeated the home favorite, but the former Wimbledon champion completed a 6-3, 7-5 win over the Canadian newcomer in a dour match that produced very little excitement. Murray, who had lost his two previous encounters with the big-serving Raonic, ensured some suspense for the last day of matches in his group, with all four players retaining a chance to progress.
