The Japanese attack on Pearl Harbor had an odd positive impact on the St. Louis baseball scene.
On Dec. 8, 1941 owners of the American League baseball clubs were set to have a meeting on the topic of moving the Browns from the Mound City to Los Angeles. But because of the attack the day before and the United States' subsequent entry into World War II, the meeting was indefinitely postponed and St. Louis remained a Brownie town for the next 12 years.
If not for the attack, the only all St. Louis World Series would have never happened. The Cardinals defeated the Browns in 1944. The Birds appeared in four Fall Classics from 1942-46 winning three. It was the Brownies' only World Series appearance. They moved to Baltimore and became the Orioles in 1953.
I wonder how different the baseball landscape might have been if the Browns moved to L.A. Would the Dodgers move from Brooklyn and the Giants from New York in 1957 if the Browns had already set up shop there? Instead, it's likely that the American League would have moved another team west to ease travel costs...
