he America's Cup is returning to San Diego for a celebration on Sunday.

Sailing's most-coveted trophy will be in San Diego with the BMW Oracle team that reclaimed it last week with two straight race wins over the Alinghi defenders from Switzerland.

The races were sailed off Valencia, Spain.

The BMW Oracle team spent 16 months in San Diego tuning its 90-foot trimaran for its America's Cup duel against Alinghi's catamaran, although the team represented San Francisco's Golden Gate Yacht Club in the America's Cup. Eventually, the trophy will reside at the Golden Gate club.

BMW Oracle boss Larry Ellison, CEO Russell Coutts and helmsman James Spithill have said San Diego is where the team perfected sailing the demanding trimaran that was powered by a 243-foot hard-wing rather than traditional sails.

Sunday's ceremonies will begin at 4 p.m. on the USS Midway with the unveiling of the America's Cup, which called San Diego home from 1987-95. The formal ceremonies start an hour later on the Midway with Mayor Jerry Sanders proclaiming Larry Ellison Day in San Diego.

At 6, the crew will board the America, the replica of the 1851 schooner for which the cup is named, to be transferred to San Diego YC for a 7 p.m. reception.
