On New York Showcase Day at Belmont Park last month, many of the New York-breds competing in the seven stakes were sired by out-of-state stallions.
Sunday's New York Stallion Stakes Series at Aqueduct, on the other hand, features the progeny of New York-based stallions.
The horses competing in the four Stallion Stakes, which are worth a total of $450,000, must be sired by registered New York stallions who were nominated to the series the year of the horse's conception. The foal's owner is then required to keep the horse eligible to the series.
