Del Mar is revamping its pick-six format this summer to mirror a long-standing structure currently in place at Santa Anita. The track will have a 20-cent Rainbow pick six, with a portion of the pool placed into a carryover until there is a single winning ticket, or until a program is designated for a mandatory payout. The format change was part of a lengthy discussion about the summer meeting from July 16 to Sept. 6 at the California Horse Racing Board’s monthly meeting on Wednesday. The racing board unanimously approved the track’s license. Craig Dado, the track’s marketing director, said the Rainbow pick six at Del Mar will have a mandatory payout on the Pacific Classic program on Aug. 21 and on closing day, which is required by state regulation. Previously, Del Mar had a pick-six structure with a $2 minimum that included a carryover when no ticketholders selected six winners, and a smaller single-ticket jackpot pool that had a carryover if there was more than one winning ticket. The track recently announced plans to have full capacity in its seating area, which can accommodate approximately 15,000 fans, and could expand maximum attendance this summer, pending conversations with state government officials, according to track president Josh Rubinstein. :: Bet the races with confidence on DRF Bets.

Del Mar has scheduled a 31-day meeting, consisting of two three-day racing weeks to begin the season from July 16-18 and July 23-25 before settling into a four-day racing week during most of the remaining weeks. Wednesday, Rick Arthur, California’s equine medical director, gave his final report before his retirement at the end of the month. Jeff Blea, a longtime practicing veterinarian at Southern California Thoroughbred tracks, will take the position in early July. During Arthur’s tenure, the racing board implemented several notable regulations, some controversial, that included the right for official veterinarians to void claims when horses were found to be unsound in post-race examinations, enhanced reviews of racing fatalities, reduction in the use of anti-inflammatories, the elimination of anabolic steroids, and restrictions on joint injections. Arthur, often an outspoken figure, was praised by racing board chairman Greg Ferraro, who like Arthur is a former racetrack practicing veterinarian. “In the last 15 years, our medical program and health and safety program are light years ahead from where it was when he started,” Ferraro said. The board approved the transfer of one week of the Cal-Expo fair meeting in Sacramento to Pleasanton for July 16-18 and the final two weeks of that meeting during two three-day racing weeks to Golden Gate Fields from July 23-25 and July 30-Aug. 1. Fair association officials emphasized that this is a one-year arrangement caused by the cancellation of the Cal-Expo fair this summer because of the pandemic. The racing board discussed a proposal for pari-mutuel sports fantasy wagering scheduled to be offered beginning in August at some satellite wagering facilities. Racing board officials acknowledged that the regulatory agency would not supervise the wagers. Executive director Scott Chaney described the legality of the wagers as “murky.” “It’s unclear who regulates it,” Chaney said. The sports fantasy wagering concept is independent of a sports wagering ballot measure scheduled before California voters in the state in November 2022.
