Astros fans who have cut the cable TV cord can still watch Astros games live this season. Exactly how depends on whether you live in or near Houston or elsewhere in the US.

In 2019, most Astros games will be shown on AT&T SportsNet Southwest. Among the major live TV streaming services, only FuboTV offers AT&T SportsNet Southwest. That makes it the only option for streaming those games live.
