Roger Federer qualified for the semi-finals of the ATP Finals on Tuesday with a 7-6(6), 5-7, 6-1 win over Alexander Zverev.
The win means Federer is now 2-0 in London and has now qualified for the last four on 14 of his 15 appearances at the Finals.
“I’m extremely happy. It’s been a tough group so to be there in two matches is great,” Federer said.

Third seed Zverev started strongly, earning three break points in Federer’s opening service game, but the Swiss Master saved them all before holding serve.
The rest of the set went with serve through to a tie-break, which Federer took after winning eight of the final 10 points.
Zverev stayed competitive, eventually levelling the match when he broke Federer for a second time at 5-6 in the second set.
But the 36-year old legend found another gear in the final set, breaking Zverev three times as he raced away to clinch the match.
Federer’s win clarifies proceedings in the Boris Becker Group after Marin Cilic was eliminated following his loss to Jack Sock earlier in the day.
With Federer already through, the winner of Thursday’s match between Jack Sock and Zverev will join him in the semi-finals.
