There are more good baseball movies than any other sport and it might even be true if you expand that to combine all the other sports together, although I will not stand behind that statement. If baseball is a popular sport to tackle in movies, well you’d think it’d be a popular subject to tackle in TV shows. And... it kind of is! I’m sure there are more explicitly baseball-themed shows, but the only one that comes to mind is Pitch, which I have never seen, but was decently reviewed before it got cancelled after just 10 episodes.
But I am aware of plenty of shows that aren’t about baseball that took an episode or two to talk about baseball.
