Zverev beats Cilic in impressive ATP Finals debut
LONDON, Nov 12 (Reuters) - German 20-year-old Alexander Zverev marked his ATP Finals debut with a 6-4 3-6 6-4 victory over Marin Cilic on Sunday.
The world number three, the youngest qualifier for the season-ender for nine years, appeared to be fading after a dazzling start, but surged back in style.
With Cilic serving to stay in the match Zverev produced a stunning backhand winner to earn three match points and needed only one of them, crunching away an easy volley to win.
Defeat left Croatian Cilic, beaten in this year's Wimbledon final by Roger Federer, with a miserable 1-6 career record in the London season-ender.
Zverev, bidding to become the first German to finish the year in the world's top three since Boris Becker in 1994, will face a mouthwatering clash with Federer on Tuesday.
