Bruce–Mahoney Trophy

The Bruce–Mahoney Trophy is a trophy awarded annually to the winner of an annual sports competition series between Sacred Heart Cathedral Preparatory and St. Ignatius College Preparatory in San Francisco, California. The two Catholic high schools are longtime cross-town rivals. Although the athletic rivalry between the schools first began with a St. Patrick's Day rugby game in 1893, and is the oldest high school rivalry west of the Rocky Mountains and the oldest Catholic School rivalry in the nation, the Trophy, in its 78th year and named in honor of an alumnus of each school — Bill Bruce and Jerry Mahoney, both of whom were killed in World War II — was inaugurated in 1947, with its first "awarding" retroactive to the end of WWII and the 1945-46 season.
