Street Magician returned $7.20 to win.\nJockey Julian Pimental sent Street Magician to the front when the gate opened on the field of six. Pimental asked the 5-year-old son of Street Cry for his best in upper stretch and he drew off to win by 2 3/4 lengths. Favorite Tempo Five finished second, a neck in front of Rouse the Cat in third. \nTen horses were entered in the event, but four late scratches Carnack's Choice, Drunken Love, Honest Trip, and Man of Danger left a filed of six.
