Marshall Cassidy (1945 - ) is an American Thoroughbred racing official based in New York State, and a former public address announcer and sportscaster. Cassidy is currently a patrol and placing judge for the New York Racing Association, and has also served as an alternate steward.
Cassidy is best known for the 18 years he spent as one of the race callers for NYRA, at Aqueduct Racetrack, Belmont Park and Saratoga Race Course. He worked as backup track announcer to Dave Johnson and Chic Anderson. Cassidy became lead announcer after the death of Anderson in March 1979.
Cassidy was the most prominent announcer in racing in the early-to-mid 1980s, not only for his on-track work but also as a sportscaster calling races for WCBS radio, CBS television, ABC television, NBC television and ESPN television. He was best known for his accuracy, precise diction and upbeat delivery, especially early in his career when calling a close race as the horses ran down the stretch.
Cassidy remained the lead race caller for NYRA until 1990, when he was replaced by present track announcer Tom Durkin. Cassidy called the fourth race at Saratoga Race Course on September 1, 2008. The race was won by Tommasi.
He is part of a well-known family of racing officials. His maternal grandfather, Marshall Whiting Cassidy, was a race starter and later steward who eventually became racing director for NYRA’s predecessor agencies, and later executive director of The Jockey Club.
The current Marshall Cassidy's maternal great-grandfather, Marshall (Mars) Cassidy, was also a fixture in New York racing as a race starter and the first to use a barrier to start a race.
George Cassidy, the grand-uncle of the current Marshall Cassidy, was a race starter for some five decades (mostly at the NYRA tracks) until he retired late December 1980.
