OZONE PARK, N.Y. – Jockey Javier Castellano, the leading rider in the nation in terms of purse money won, on Saturday will begin serving a seven-day suspension for careless riding stemming from an incident last year. Castellano dropped his appeal of a suspension handed him by the New York stewards for his ride aboard Intense Holiday in last year’s Grade 2 Nashua Stakes. Castellano maneuvered Intense Holiday over to the inside and forced the rider on Tiznowforamerica to check and nearly go into the rail. Intense Holiday finished fourth, and Tiznowforamerica was last. The stewards did not make a change to the order of finish in the race.
