Free's preview: All-Polytrack card
The temporary cancellation of turf racing at Del Mar means pure Polytrack for at least the next week. Track officials announced Friday that turf racing will not resume until Aug. 9 at the earliest. The change affects three races Saturday that were scheduled for turf. It also lessens the appeal of the card, and the meet. Turf races historically account for 30 percent of the Del Mar program.
