The London Majors first joined the Senior Intercounty Baseball League (IBL) as the London Braves in 1925 and promptly won their first Sr. IBL Championship that same year with a team managed by former minor pro short-stop and relief-pitcher Gil Forgue (1888-1979). In 1928, the IBL team was the London Red Caps, from 1934-36, the IBL team was the London Winery; in 1937, the London Silverwoods. They went from beer to wine to milk, but in the 1950s, the team drank ice-cold Labatt's 50 Ale.
Over the years, London's IBL franchise has had a variety of names, including London Braves in 1925, London Red Caps in 1928, London Winery from 1934-1936, London Silverwoods in 1937, London Seniors in 1938, the London Army Team from 1942-1943, London Majors from 1944-1959, London Diamonds from 1960-1961, London Majors again in 1962, London Pontiacs from 1963-1969, London Avcos from 1970-1973 and London El-Morocco Majors in 1974.
Since winning the IBL Pennant and IBL Championship in 1975, the team has stuck with the military name, London Majors, a moniker first coined by Captain Chet Smith, manager of the 1943 London Army Team, IBL, OBA Sr. 'A' and Canadian Baseball Congress Champions.
In 2020, the Majors season was cancelled due to the global COVID-19 Pandemic. Between the efforts of the Majors, City of London, Middlesex Health Unit and Guelph Royals, the longevity of the World's Oldest Active Ball Grounds could continue. The Majors' dominant pitching led the team to a 3-0 victory. This game was known as the Legacy Classic. LEGACY CLASSIC (SHORT VIDEO)
