AP Source: GM to end sponsorship of Buick Open

DETROIT – DETROIT (AP) - A person briefed on the decision says this week's Buick Open golf tournament will be the last because General Motors Co. will end its sponsorship after more than a half-century.

The person said GM and tour officials will announce after the tournament that GM is pulling out. The person did not want to be identified because the announcement has not been made.

The troubled automaker has been cutting back on professional sports sponsorships for the past year as it tries to focus more marketing dollars on its cars and trucks.

Last year GM ended a nine-year endorsement deal with golf superstar Tiger Woods, who will play in this week's event in Grand Blanc, Mich., about 50 miles north of Detroit.
