The city of Stockton is home to the largest inland seaport in the state of California. The Port of Stockton, roughly 80 miles east of San Francisco Bay on the San Joaquin River, officially opened in 1932, but the city has played host to seafaring vessels since the 1860s. It’s because of this that the High-A California League Oakland A’s affiliate in town has its name.
And it’s for this reason that one of the logos that minor league baseball’s Stockton Ports has used since 2002 features a tugboat against the letter S.
Earlier today, the Ports, Low-A affiliate of the Oakland A’s, unveiled a new batting practice cap featuring a modified version of that tugboat, now standing alone on a black cap with a red brim. The team will use the new cap starting with the 2022 season, which begins April 8.
