Good recent turf form is a scarce commodity in Saturday’s $75,000 Dahlia Stakes at Pimlico. Of the 11 fillies and mares entered in the one-mile turf race, five are coming off layoffs of more than 60 days and four others have been off for more than a month. The only two horses who have run within the past 30 days are both switching surfaces and have a combined total of just two lifetime starts on grass.
