Sunday 10th April 1921

Jimmy Murphy drove his Duesenberg to victory in a 50 mile AAA Championship race at Los Angeles Motor Speedway. Duesenberg drivers Murphy, Joe Thomas and Eddie Pullen won earlier 25 milers as did Ralph DePalma in a Ballot. It was the last AAA wins for both Pullen & DePalma. DePalma’s 24th AAA win set a mark for career Indy Car wins not surpassed until 1963 .
