I was looking at the ATP rankings and which year they turned pro and I couldn’t understand what the criteria for players to be able to turn pro was?
I always thought that as soon as a player start to play ITF World Tennis Tour and earn some prize money, he is automatically is considered to be a pro. But I noticed that every single player had already been playing 1-2 years on the ITF World Tennis Tour and had a certain ranking before they turned pro. Normally it was happening when they were achieving at least top 1000 ranking.
Can someone please explain what the criteria is for players to be able to turn pro?
