The PGA Tour suffered a double blow on Tuesday because of the economic downturn with the removal of the Buick Invitational and Buick Open golf tournaments from its 2010 schedule. In a long anticipated move, troubled Detroit automaker Buick announced in a joint statement with the Tour that it had withdrawn its sponsorship of both events from next season. The statement read: “... as a result of the recent court-supervized restructuring of General Motors, all agreements between Buick and the PGA Tour have been withdrawn. “This brings to an end the Buick Open at Warwick Hills, (Grand Blanc, Michigan) and Buick's sponsorship of the Buick Invitational at Torrey Pines, (LaJolla, Calif.). “While this is disappointing news, both the PGA Tour and Buick remain in discussions regarding future sponsorship possibilities.” The PGA Tour said it would make an announcement on Wednesday regarding a replacement event for the Buick Open, which is widely expected to be staged at The Greenbrier in West Virginia.
