AKRON, Ohio: Title sponsorship of the WGC-Bridgestone Invitational has been extended for a further four years, keeping the elite World Golf Championships (WGC) event at Firestone Country Club until 2014.

"I think the happiest person today might be Tiger (Woods), winning 60 or 70 percent of the time he plays here," PGA Tour commissioner Tim Finchem told a news conference.

The PGA Tour has lost four title sponsors this year due to the global economic downturn and Finchem was delighted by the tire company's decision to extend the contract.
