Every once in a while, there seems to always be a teenager who goes on to beat a top-ranked player whether it be a 19-year-old Roger Federer over Pete Sampras in 2001 or a 19-year-old Nick Kyrgios over Rafael Nadal last year.
This time, it's Novak Djokovic's turn to lose to a teenager in the form of 18-year-old Alexander Zverev of Germany. Zverev had a convincing victory 6-4, 6-3 over Djokovic at The Boodle's, an exhibition-type tournament in Buckinghamshire, England.
Zverev broke Djokovic in the opening game with some precision hitting from the baseline and followed it up by holding serve. During the closing game of the first set, Zverev relied on heavy serves to beat the Serb and even showed character when he started joking with one of the linesmen.
When asked how it felt to beat the world number one, Zverev had a very relaxed response: "Uh, normal?"
Djokovic on how impressed he is with the teen: "Very."
