Career
Pratt, born in Highgate, Birmingham, joined Small Heath in 1889. A winger whose strengths were dribbling and crossing the ball but who lacked pace, he made his first-team debut on 19 October 1889, playing at inside left in a 2–2 draw away at The Wednesday in the Football Alliance. He became a first-team regular in the 1890-1891 season, but lost his place to new arrival "Toddy" Hands in December 1890, played only twice more for the first team, and dropped back into local non-league football in 1892.
He is often confused with another Billy Pratt, a left back who did not join the club until 1894.
