William Sinclaire

William “Bill” Sinclaire served as a mentor for many who thought polo was a game worth playing and promoting. He was instrumental in reviving polo in the Rocky Mountain area after WWII by building a field and organizing local ranchers and horsemen into polo teams.

His decades-long involvement with clubs in the Denver, Colorado, area – along with his participation in high-goal polo – gave him a unique perspective on the needs of players and clubs across the United States. Serving as an executive of the USPA for fifteen years, his positions included USPA governor (1969-1971), treasurer (1971-1973), vice president (1973-1976), president (1976-1980) and ultimately as chairman (1980-1984). He was known as a fair and unbiased administrator and dedicated to the well-being of the sport.

Bill was a member of the winning U.S. team in the Camacho Cup series with Mexico in 1975, won the Butler Handicap in 1976, and won and competed in numerous other club and USPA tournaments. For his stewardship and his loyal services to polo, he was awarded the 1989 USPA Hugo Dalmar Sportsmanship Award.
