Get a large bottle of wine (or other favorite spirit), clear your calendar for about 2 weeks, and then put the words "Beast", "VEMmie" or "Deviations" in the search box to the right.... ------>
You'll see that this is a designed feature of the game to make it realistic. We, as real world golfers, know that the ball isn't going exactly where we aim, so the game adds a bit of randomness to each shot. (Precision of equipment matters, too.)
Should you want to try to play "Target golf", where each shot goes exactly where you planned it (and you're given a free preview to see where it's going to end up) there is another game just down the road put out by EA Sports.
Some of us prefer a bit o' realism in our sims... (as oxymoronic as that sounds.)
Hope that helps. Any other questions just fire away!
Peace.
