The Sony Open turned solemn Tuesday morning when dozens of players, caddies and PGA Tour officials joined Grayson Murray's family along the shore behind the 16th green at Waialae to pay tribute to the defending champion who took his own life four months later. Murray won the Sony Open last year by making birdie on the 18th hole and winning a playoff with a 40-foot putt. The celebration of his life took place one day after the PGA Tour announced the launch of the Grayson Murray Foundation, which is geared toward raising awareness and support of mental health and addiction.
