From the Del Mar Media Team: Del Mar Thoroughbred Club has announced it will run a make-up day of racing on Monday, August 31. It expects to present a 10-race card starting at 2 p.m. The added date means Del Mar will finish up its 2020 summer race meet with two four-day weekends -- August 28 to 31 and September 4 to 7. On the heels of a recently announced 10% purse increase, the seaside track's extra day will bring the number of race days for its 81st summer season to 27. Originally, 28 racing days had been planned. The track’s racing office has been adding extra races to its regular cards to make up for the lost date as the meet moves through its scheduled Friday through Sunday timetable.
