The PGA Tour is searching for a new sponsor for the World Golf Championship event at Doral after software company CA chose not to extend their deal.
The business software company said in a joint statement with the PGA Tour that they were ending their backing of the event which was won on Sunday by South African Ernie Els.
The PGA Tour commissioner Tim Finchem says he hopes to find a new backer for the tournament, which is one of four annual events making up the World Golf Championships.
The event has been held since 1999 and was sponsored by CA from 2006.
It has featured at Doral since 2007 having previously moved from different venues in the United States and Europe.
It replaced the Doral Open which had been part of the PGA Tour from 1962.
