Aqueduct stewards hit Rajiv Maragh with a 15-day ban for his role in Friday's spill that hospitalized Pedro Monterrey Jr. Maragh, a five-pound apprentice who figures to compete for honors as top bug rider this winter, has appealed the suspension and should be able to put off a hearing until the winter meet winds up in March.Maragh was aboard Greatlengths U S A in Friday's opener when he allowed his mount to drift in front of Prince Peapa, ridden by Monterrey. Monterrey was unseated, starting a three-horse chain reaction spill. The stewards' ruling cited Maragh for "gross careless riding."As for Monterrey he was at Aqueduct early Saturday toting a sling on his right shoulder as a precaution. His only scheduled mount on the day was scratched and his only scheduled mount for Sunday is an also eligible. He was named to ride five horses on Wednesday's card, which was drawn Saturday.
