Focusing on your right arm can be the way to save your short game- especially the pitch shot and chips from near the fringe. Watch this video to learn how players such as Jason Day eliminate the bad short game shots via their technique
Luke Donald has always been recognized with having one of the better short games on tour. He recently posted a video showing his pitching action- and a great way to train how to use the bounce correctly.
