Fred Whitcroft played for the Peterborough Colts when they won the OHA junior championship in 1901, and he was a rover for the intermediate Colts when they captured the provincial championship five years later.
When Thomas Hooper of the Kenora Thistles was looking for a rover to strengthen his team for a defense of their Stanley Cup title, Whitcroft's name was mentioned. The necessary arrangements being made, Whitcroft was in Kenora for the end of the 1907 season as a member of the Thistles in the Manitoba Pro League. Although their line up was bolstered with the additions of Whitcroft, Alf Smith, and Harry Westwick of Ottawa, Kenora could not hold off the challenge from the Montreal Wanderers and surrendered the Cup in March 1907.
Whitcroft moved to Edmonton the following season and led the APHL with 35 goals in ten games. The Edmonton team challenged for the Stanley Cup in December 1908 and again in January 1910 but was unsuccessful on both occasions. Whitcroft left Edmonton after the challenge series and finished his career with the Renfrew Creamery Kings of the National Hockey Association.
After his retirement at the end of the 1910 season, Whitcroft returned to Edmonton to manage the hockey team for two seasons.
Fred Whitcroft was inducted into the Hockey Hall of Fame in 1962.
