You will probably get this playing through your career if you are going for as many Elite ratings as you can. If you haven’t you can begin a game on Free Play, easy pins and choose the par 5 courses. Par 5’s are a little more forgiving as long as you are hitting long and accurate for your first couple of shots. Try to stay on the fairway and use your golfer’s ability if you are struggling on a hole. Reiko’s Tesla Field ability is extremely helpful here.
Choose your caddy depending on where your weakest, if it’s putting take Astrid and if it’s the approach take Kirby. Once the game is over if you have scored under par the achievement will unlock.
