The stream is about to begin flowing for Cardinals fans.

Fox Sports Midwest has finalized a deal in which it will offer online and mobile streaming of its telecasts of Redbirds games this season, via the Fox Sports Go website and app. However, this streaming will be available only to those who subscribe to a programming provider that carries Fox Sports Midwest and register with Fox Sports Go.

There won’t be an additional charge for the streaming service, which is to begin with the regular-season opener — April 3 in Pittsburgh — and include all of the approximately 150 Redbirds games FSM is set to show. (Card contests shown by national networks also will be streamed, on Fox Sports Go or ESPN3.)

A Fox Sports Midwest spokesman said three of the four major programming providers in the St. Louis market — Charter cable, DirecTV and AT&T U-verse — are set to be on board from the start. However, Dish Network is not expected to offer streaming until later in the season. Many of the smaller systems in the area also will be have streaming and that list is to expected to be available next week.
