In 1878 it was bought by David D. Withers, George L. Lorillard, James Gordon Bennett, Jr., and George P. Wetmore. From 1882 to 1890, the track increased in popularity, but legislation proposed in 1891 and enacted in 1894 barred parimutuel betting in New Jersey, and the track closed its doors. In May 1894, the Township Committee at Eatontown, New Jersey ordered the seizure and sale of the Monmouth Park Association's grandstand and other property for the payment of back taxes and on May 7 was sold at a public auction.
