I'm convinced this wouldn't happen. At this speed, only direct collisions of nuclei would do anything. The ball would pass through the air and bat as if they weren't there... and I don't believe it would deposit an appreciable amount of energy at any particular place... If you think I'm wrong, just think about how far high energy protons (cosmic rays) travel through our atmosphere before they lose their energy. Each atom of the baseball has a good probability of flying through the air for a substantial distance before interacting with anything at all.
