Federer into ATP semifinals

A day after the ATP Finals lost Rafael Nadal to injury, Roger Federer lifted spirits at the London event by extending his stay. The 19time Grand Slam champion guaranteed his place in Saturday’s semifinals by defeating Alexander Zverev 7-6 (6), 5-7, 6-1 on Tuesday.

Zverev, who won his opening match against Marin Cilic, will face Jack Sock on Thursday to decide who will join Federer in the final four. Sock recorded the United States’ first victory at the event in 10 years by defeating Cilic 5-7, 6-2, 7-6 (4) in the early match, with the Croat later eliminated by Federer’s victory. Sock lost his debut match to Federer, and is 1-1.
