Federer through to ATP Finals semis
A day after the ATP Finals lost Rafael Nadal to injury, Roger Federer lifted spirits at the O2 Arena by extending his stay to the weekend.
The 19-time 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 for 10 years by defeating Cilic, 5-7, 6-2, 7-6 (4) in the early match, with the Croat later being eliminated by Federer’s victory.
