World War II threatened to ruin Major League Baseball. By 1945, over 500 major leaguers and 3,000 minor league prospects had been enlisted for the war effort, leaving a dearth of talent for the Big Leagues. The St. Louis Browns, like other AL and NL clubs, would be forced to fill holes in their roster with scrubs-4-F players (those dismissed from the military due to physical ailments), retired major leaguers, and youngsters not yet ready to leave the minors. But there were still some top level players to be had, and 1944 Browns manager Luke Sewell assembled the franchise's most successful team ever, taking the St. Louis ball club to its first and only Fall Classic.
