Cale Hammond is a former Duke Tennis player and failed professional tennis player. He recently quit his job as a writer and betting analyst for Tennis Channel to focus on tennis investing full-time.

“Tennis is by far the best sport in the world to bet on. You have an 11-month season, and I am pretty keyed in to the tour so I can find out how the conditions are playing at most professional tournaments. Tennis is the second-most bet on sport globally behind soccer, and it’s easy to see why. The options and opportunity for profitability are tremendous.”

Hammond’s goal is to grow the incredible game of tennis through gambling, though he prefers the term investing.
