SAN MATEO, Calif. - Saturday's $100,000 California Sprint Championship, a six-furlong race for Cal-breds, often serves as a prep for the Cal Cup at Santa Anita. This year's race has attracted a varied group of seven, ranging from Chataquos' Choice, a moon-shooting 3-year-old who just won his maiden in a claiming event, to 10-year-old millionaire Men's Exclusive.
