Two-time PGA Tour winner Grayson Murray died Saturday morning at age 30, one day after he withdrew from the Charles Schwab Challenge at Colonial.

There were no immediate details on the circumstances of his death, only shock and grief from the PGA Tour and his management team.

"I am at a loss for words," PGA Tour commissioner Jay Monahan said in a statement. "The PGA Tour is a family, and when you lose a member of your family, you are never the same. We mourn Grayson and pray for comfort for his loved ones."

His management company, GSE Worldwide, confirmed the death.

"We will hold off on commenting until we learn further details, but our heart aches for his family, his friends and all who loved him during this very difficult time," GSE said in a statement.

Jay Green, Murray's caddie, lamented the loss of his "friend" in a statement to the Golf Channel.

'Grayson was the absolute best. Not only was he an incredible, thoughtful and generous boss, he was an even better friend," Green wrote.

'He truly would do anything for anyone. He has the best family, and my heart goes out to them. We will all miss him deeply.'

Monahan said he spoke with Murray's parents to offer condolences, and they asked that the tournament in Fort Worth, Texas continue. The tour cited illness when Murray withdrew from Friday's second round.

Monahan said grief counselors would be on-site at the PGA Tour and Korn Ferry Tour event. He also said he was headed to Texas.

Murray, who spoke about alcohol and mental health in the past, made a massive turnaround this year and won the Sony Open, hitting wedge to 3 feet for birdie on the final hole to get into a playoff and winning it with a 40-foot putt.

He had won the Barbasol Championship in 2017.

Murray, who was No. 58 in the world ranking, was coming off a tie for 43rd in the PGA Championship last week at Valhalla. He also made the cut in his Masters debut, finishing 51st, and was in the field for the U.S. Open next month at Pinehurst No. 2.

Murray, who grew up in North Carolina, was among the most talented juniors in the country. He won the prestigious Junior World Championship in San Diego three straight years and earned the Arnold Palmer Scholarship at Wake Forest.

He wound up going to three colleges, lastly at Arizona State, and won as a 22-year-old PGA Tour rookie at the Barbasol Championship.

Murray said when he won the Sony Open in January that he had been sober for eight months, was engaged to be married and felt his best golf was ahead of him. He was appointed to the 16-member Player Advisory Council.

"My story is not finished. I think it's just beginning," Murray said in Hawaii. "I hope I can inspire a lot of people going forward that have their own issues."

Murray said he used to drink during tournament weeks as a rookie because he knew he had talent and felt he was invincible. He also brought attention to himself through social media, openly criticizing other players and getting into one social media spat with Kevin Na over Na's reputation as a slow player.

But he felt like he turned the corner when he sought help - letting others fight for him, is how he explained it this year.

"It took me a long time to get to this point," Murray said in January. "That was seven years ago, over seven years ago. I'm a different man now. I would not be in this position right now today if I didn't put that drink down eight months ago."
