Although baseball has been played in Stockton for over 100 years, the Stockton Ports didn't come into play until 1941 as the Ports were one of the founding members of the California League. The Ports gained their unique name from the cities own rich history and strong resource as the states only inland Port.
In 1946, after the war, the league re-established itself with teams in Stockton, Bakersfield, Fresno, Modesto, Santa Barbara and Visalia. The California League would then add another two teams for the 1947 season in San Jose and Ventura. Today, the Ports are a part of a ten team league with teams in Modesto, San Jose, Visalia, Bakersfield, High Desert, Inland Empire, Lancaster, Lake Elsinore and Rancho Cucamonga.
Over the course of the Ports 61 years as a member of the California League, they have won 11 titles (most by any active team, Reno franchise has 11) and have posted an overall 4,474-4,018 record and made it to the postseason in 38 seasons.
The Ports are the fastest team in Cal League history to reach the 4,000 win plateau, a feat they accomplished in 2004. The Ports Championship years have come in 1946, 1947, 1963, 1965, 1969, 1980, 1986, 1990, 1992, 2002 and 2008.
Stockton remained in the California League through the 1972 season and then returned in 1978. During the 1980's and into the 90's the Ports were America's winningest Professional Minor League Baseball team with 977 total wins through the 1991 season and would then win the Cal League title in 1992. The Ports also captured the Cal League Championship in 2002, and again in 2008.
