If Fovee runs back to her dazzling comeback win last month, Saturday night’s Grade 1, $150,000 Mildred Vessels Memorial Handicap for Quarter Horses at Los Alamitos could turn into a race for second. In all, a field of 10 fillies and mares will start in the 400-yard dash that provides its winner with a berth into the Grade 1, $750,000 Champion of Champions.
