This can either be done in standard tournament mode or during career where it is the seventh and final tournament on the calendar. Six matches have to be won in total and the tournament format is as followed.
1st round - First to 3 sets
2nd round - First to 4 sets
3rd round - First to 4 sets
Quarter-Finals - First to 5 sets
Semi-Finals - First to 6 sets
Final - First to 7 sets
3 legs are needed to win a set in all matches.
The main issue with this and all the tournament achievements is it has to be done in one sitting without turning off your console, without returning to main menu and without saving mid-match. Doing any of these glitches the achievement and you will have to do the whole tournament again.
