A four-day holiday weekend at Portland Meadows in Portland, Ore., kicks off Friday night with the Powder Puff Derby.
The six-furlong race for $4,000 claimers who have never won two races drew a field of six. Each entrant in the race for older fillies and mares will have a woman jockey.
Portland Meadows officials hoped to find eight entrants for the race so that all eight of the local women riders could compete.
