Del Mar's 84th summer meet begins Friday with a sell out and the traditional opening day features -- the hat contest in the Plaza de Mexico and the Caesars Sportsbook Oceanside Stakes. "This will be the third year we've capped attendance on opening day and the feedback we have received from our fans over this time has been overwhelmingly positive,'' said Del Mar CEO Joe Harper. "A sell-out crowd where everyone has easier access to wagering, food and beverage and other amenities is the right way to get our 84th racing season off to a strong start.''
