With legendary “Big Money” Mike Smith dealing the cards on the front end, 9-1 longshot Mirth registered an impressive 1 ¼ length victory in Saturday’s Grade I, $300,000 Rodeo Drive Stakes at Santa Anita. Trained by Phil D’Amato, who won the Grade II John Henry Turf Championship earlier in the day, Mirth, a 4-year-old Pennsylvania-bred daughter of Colonel John, got a mile and one quarter on turf in 1:58.47.
