On-track attendance totaled 44,907, the largest crowd in Del Mar history, eclipsing the previous record of 44,181 set in 1996 when Dare and Go upset Cigar in the Pacific Classic. Last year's attendance on opening day was 43,459.

Wednesday marked the first day that Del Mar's new betting platform, DelMarBets.com, handled action on racing at Del Mar, as well as other tracks around the country. The betting service recorded a spike of several hundred sign-ups over the course of the afternoon, most taking advantage of the Bet $100 Get $100 offer provided to all new accounts.
