This can be obtained even if you don’t have a friend who plays the game. If that’s the case, here is how it’s done.
Select a TGC Official course, a short one is Blue Ridge Golf Club which is only nine holes. Play a round and set a score that isn’t good, one you know you can beat. After that round is complete and recorded start up another round.
When you beat your previous score and the round is over the achievement will unlock.
