Stan Musial, born into an unfortunate era of war, was not exempt from the duties of fighting for his country. He was also just following an incredible year in 1944 where he led the league in slugging percentage (.549), on-base percentage (.440), WAR (9.3), and wRC+ (174). Along with that he was also 2nd in batting average (.347). All while leading the St. Louis Cardinals to their second World Series title in three years as they beat St. Louis Browns in an all-St Louis World Series matchup.
*Fun fact about the 1944 World Series is that it is the only World Series to not have a single successful stolen base recorded.
