Losing out on almost four years of Baseball service due to World War II, Hank Greenberg still managed to be a two-time American League MVP and a four-time Home Run Champion. Greenberg was an incredible slugger, posting eight seasons where he eclipsed .600 in Slugging and his incredible Slash Line of .319/.414/.616 is nothing short of incredible. Greenberg is also a two-time World Series Champion.
