Moe Berg played major league baseball for 15 seasons in a mostly undistinguished career. The Ivy League-educated lawyer made his real contribution in espionage, working with the U.S. government to help win World War II, helping to prove that the Nazis were failing to develop their own atomic bomb.
ESPN’s 30 for 30 series just debuted Spyball, a short film that tells Berg’s amazing story. Watch the movie embedded below. If you like the movie, you can also check out The Catcher Was a Spy, Nicholas Dawidoff’s outstanding 1994 biography of the man that manager Casey Stengel called “the strangest man to ever play the game of baseball.”
