The Los Santos Squeezers is a baseball team appearing in Grand Theft Auto V.
Not much is known about it, but Franklin can purchase Squeezers branded clothing at SubUrban. It is possible to be based on the Los Angeles Angels, another Los Angeles pro baseball team. But it also may be a minor league.
A pedestrian can be found wearing a black hat with the "S" logo of Squeezers.
The player can also set the background of their phone to the Squeezers logo.
The GTA Online character can purchase a Squeezers baseball shirt in any clothes store. There is a date written on the shirt, however, it is difficult to read.
