I have said at least a few times in the past that Phil Mickelson has never changed his swing. He has claimed that he has done this and that but his standard pattern has remained the same, and the video has proved it. Recently, however, he has changed teachers and touted a “new plane”, a statement I disagreed with earlier in the year. But, after watching him at the British Open and studying his more recent swings, I now agree with his assessment that he has changed his action significantly for the better, as you will see in this video.
