Set up a tournament using the following settings: Quick play/Quick tournaments/Masters Tournament/Augusta National/In The Hunt scenario. Select your created golfer for yourself and pick Woods, Jones and Bubba Watson (Not Tom Watson) as AI. Leave the round settings as default (reset to default if needed - but check them afterwards!), and play through 18 holes. The achievement will pop when your scorecard comes up on completion of the round, and you shouldn't need to win (I would always win for good measure though).
