Pails won the men's singles championship at the Australian Championships tennis tournament in 1947. Pails, an Australian who was born in Great Britain, defeated John Bromwich in the final in five sets: 4–6, 6–4, 3–6, 7–5, 8–6. Pails played eight Davis Cup matches between 1946 and 1947, winning three matches and losing five.
Pails turned professional and played on the pro tour off and on for many years, Bud Collins ranking him the World No. 4 pro in 1948, whilst he reached as high as World No. 6 in the 1947 amateur rankings. According to tennis great and long-time promoter Jack Kramer, Pails beat Pancho Segura 41 to 31 matches in the 1948 tour, "but that was when Segoo was still learning how to play fast surfaces." Kramer himself beat Pails "55 times with 1 draw, but somehow we were able to forget that off the court." In 1954 Pancho Gonzales beat Pails 47 matches to 7.
