Jannik Sinner sparked plenty of debate after revealing that he did not play in the Six Kings Slam exhibition event for the prize money. Roger Federer’s ex-coach Paul Annacone has come to the Italian star defense, stressing that the best players take their fair share of the sports money.

Sinner has won two Grand Slams and three Masters 1000 titles this season, as well as two ATP 500 crowns. However, all his tournament victories have only earned him a little above $12 million. Meanwhile, at the exhibition tournament in Saudi Arabia, the 23-year-old won three matches and walked home with a whooping $7.5 million.
