This can either be done in standard tournament mode or during career where it is the first event of the calendar. Six matches have to be won and all the matches are the same format of best of 5 sets, 3 legs, meaning two legs have to be won to win a set and 3 sets are needed to win a match.
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.
