Robert Allenby was kidnapped, beaten and robbed on Friday night after missing the cut in the Sony Open in Hawaii at Waialae Country Club in Honolulu.
The 43-year-old Aussie, who has won four times on the PGA Tour including the 2001 Nissan Open at Riviera Country Club in Pacific Palisades, went to a wine bar near Waikiki Beach with his caddie, Mick Middlemo, and another friend after leaving the course.
Neither of the others witnessed the abduction of Allenby, who sustained significant facial injuries and was robbed of his wallet, cell phone, cash and credit cards before being left in a park six miles away.
Middlemo said a groggy Allenby had no immediate recollection of the events when he was found in the park by a retired military officer, who drove him back to the Kahala Hotel.
On Saturday, Allenby began piecing together what happened the night before and police took him back to the wine bar to look at surveillance footage.
The Golf Channel, which reported the incident during its Saturday broadcast of the Sony Open, posted a picture of the battered Allenby on Twitter.
