After an intensive 3 month rehab period, Jason Day returns to PGA Tour play with the goal of lengthening his career by shortening his swing. He also hopes that a shorter swing will prevent re-injury of his thumb, which he first hurt in 2014.
As I recall, Tiger’s latest “swing consultant”, Chris Como, was hired to specifically change Tiger’s swing in order to prevent further back injuries. Back injuries seem to be common in golf, especially among those golfers who get a large degree of separation between their hips and shoulders in the back swing.
Many amateur golfers struggle with persistent back pain, either from golf or from their jobs. Maybe we should all take a lesson from Jason and shorten our back swings so that we can play the game we love for another 30 years.
