The Hamilton Hotel is located on Hamilton Avenue in St. Louis, Missouri. The hotel served as the headquarters for the Cardinals during spring training of 1919. World War I had a huge impact on baseball and much revenue was lost during the few years the war lasted. The St. Louis Cardinals were on the bottom of the heap for many of those years and came out scrimping and saving for the 1919 season. Looking to save money wherever possible the team decided to hold spring training in St. Louis that season. Among the Cardinals living at the hotel that spring training was their star infielder Rogers Hornsby, who was on the verge of making his historic impact on the game. He remained here until the season began, when he was joined by his wife Sarah in a furnished apartment at the nearby Harlan Courts Apartments. The Hamilton Hotel was placed on the National Register of Historic Places in 2011.
