Organizers of San Diego's PGA Tour stop, the erstwhile Buick Open, are unlikely to find a sponsor before the Jan. 28 tournament, leaving the PGA Tour on the hook for much of the $5.3 million purse, according to Tod Leonard of The San Diego Union-Tribune. The Century Club had tried since August to find a new sponsor after Buick pulled its support one year early following the automaker’s bankruptcy. But negotiations with at least a half dozen companies did not produce a sponsor that would commit the $7 million to $10 million it takes each year to stage a tournament. The Torrey Pines tour stop is one of the PGA Tour's marquee events. It has become the de facto start of the PGA Tour season because it's often the first tour event of the year in which Tiger Woods and Phil Mickelson compete. Plus, Woods's legendary U.S. Open win at Torrey Pines in 2008 added stature to the course, which offers some of the most remarkable views in golf outside the Monterey Peninsula. The inability to find a sponsor this year for such a high-profile event looks like bad news for the tour, but commissioner Tim Finchem said recently he was "delighted" with the progress the tour has made on renewing sponsorships.
