Very few people on earth hit their irons more pure and consistent than two-time major champion Xander the Great.
His approach to distance control…
To hit a chippy: softer, smoooooother swing, standard set-up = 85% distance (less distance, less spin)
To hit a stock shot: focus on making solid contact and commit to your shot = 100% distance (standard distance, standard spin)
To hit a tomahawk: put the ball back in your stance which will deloft the face and make sure to let your hands fully release = 110% distance (longer distance, draw spin)
Easy.
