10. Plague of Midges

 
 

The Cleveland Indians baseball stadium, and much of Cleveland itself, is built by a lake, which often leads to some strange problems. In a playoff game between the New York Yankees and the Cleveland Indians, thousands of midges came out of the lake in huge numbers and affected the course of the game. Though they’re generally harmless, the sheer swarm seriously tweaked Yankees pitcher Joba Chamberlain to the point that he could not concentrate. The bugs ended up swinging the game for the Indians, who ended up winning their series against the Yankees. Talk about home field advantage.
