Two-time PGA Tour winner Grayson Murray has died, just one day after withdrawing from the Charles Schwab Challenge at Forth Worth, Texas.
American Murray, 30, won his most recent title at this year's Sony Open in January.
He had pulled out of the Charles Schwab tournament during the second round, citing an illness.
Murray reached a career-high 46th in the world rankings after his Sony Open win.
"We were devastated to learn and are heartbroken to share that PGA Tour player Grayson Murray passed away this morning," said PGA Tour Commissioner Jay Monahan. "I am at a loss for words.
"The PGA Tour is a family and when you lose a member of your family, you are never the same."
There are no immediate details on the circumstances of his death, only shock and grief from the PGA Tour and Murray's management team.
The PGA has announced grief counselors will be available at the Charles Schwab tournament and Korn Ferry Tour events.
