24. John Isner – Tennis
It’s hard to argue that John Isner doesn’t use height to his advantage on the tennis court, because this 6’10” has had a fantastic career.
Isner turned pro in 2007 and, since 2010, has won at least one title every year aside from 2016.
The tennis tall man is known for his devastating serves and holds the fastest serve ever recorded by the Association of Tennis Professionals (ATP) at 157.2 mph. With a long list of wins against top 10 opponents, his top ranking of No. 9 is certainly well-deserved.
