That article is kind of a joke, not really worth responding to. But in response to the title of this post, I would argue that professional baseball is exactly the kind of market where inefficiencies might not disappear quickly, since liquidity is so low. There are only 30 teams, after all. There aren't 10,000 day traders flipping baseball players, trying to get an edge.
