According to the EA Forums......a post made today (19/09/2012)

The last 'Play The Pros' tournament goes online tomorrow (20/09/2012)...This will be the last chance I believe to get this achievement....Tournament will end on the 25th of September. You must do it before then....I know I will.

EA runs a weekly play the pros tournament that simulates you playing against the real scored of pga professionals. In the xbox live menu for live tournaments, select play the pros and play a round. You need to only play one round, you do not need to submit all 4 rounds to get this achievement.
