It was wartime. Commissioner Kenesaw Mountain Landis had told his Major League franchises that they would spend the next few years training very close to home. There would be no tropical spring migrations for the foreseeable future... in fact, traveling would be kept within a rectangle north of the Mason-Dixon line and east of the Mississippi. In the Northeast... the Brooklyn Dodgers, Boston Braves, Boston Red Sox, New York Yankees and New York Giants made the best they could out of local
colleges or institutions. For the 1943 Spring Training season, the Dodgers built a makeshift ballpark in front of the Bear Mountain Inn in West Point while the Giants did the same at Rockefeller's golf course in Lakewood New Jersey (which they dubbed Ott Field). The Yankees went to Asbury Park and took over their High School's huge football stadium and the Phillies went to Hershey Pennsylvania to play in their tiny little wooden ballpark. . The Red Sox took shelter from the cold inside Tufts University's Gymnasium while the Braves did the same at Choate School in Wallingford Connecticut. With the Senators taking over UM's little ballpark in College Park Maryland, the only team to play in a proper "stadium" would be the Philadelphia Athletics who would move their Spring Training operations to the Class B Interstate League's Wilmington Park aka Blue Rocks Field.
