At this time, a number of boxers owned 'sporting saloons' that were home to gambling. These saloons capitalized on the popularity and reputation of prize winners and added income for the top boxers as the money earned in the ring was often minuscule. Yankee Sullivan opened the Sawdust Room on Walker Street which gave boxing fans a chance to meet reigning heavyweight champion. However, business at the Sawdust Room's popularity soon declined after his defeat against John Morrissey in October 1853.
This sudden declined resulted in Sullivan selling his saloon and moving to San Francisco where he became an enforcer for businessman and politician David C. Broderick. On May 20 1856, Sullivan was arrested for ballot-box fraud. Fearing the consequences of his connection to organized crime, Sullivan committed suicide in his prison cell eleven days later. There is no marker designating the location of the Sawdust Room or the short career of Yankee Sullivan.
