WATCH: Federer aces ATP Spelling Bee
It turns out Roger Federer is talented at more than just tennis.
Sky Sports held an ATP Spelling Bee with six of the ATP Finals players, and Federer nailed the names "Khachanov" and "Basilashvili."
Alexander Zverev did well, too, getting "Khachanov" and "Kohlschreiber." However, he did misspell the name of fellow German Peter Gojowczyk.
Still, it's hard to blame someone for not knowing the correct order of the letters "wczyk."
Marin Cilic, though, notably managed to spell "Gojowczyk" correctly.
Federer is 1-1 after three days of play in London, having lost his opener to Kei Nishikori but scoring a win over Dominic Thiem 6-2, 6-3. Zverev is 1-0 after a 7-6 (5), 7-6 (1) win over Cilic.
