Albert Leonard Rosen (February 29, 1924 – March 13, 2015), nicknamed "Flip" and "the Hebrew Hammer", was an American professional baseball player and executive. He played his entire career in Major League Baseball (MLB) as a third baseman for the Cleveland Indians from 1947 to 1956.
After serving for four years in the U.S. Navy during World War II, Rosen returned to become a stand-out for the Indians on both offense and defense. A four-time All-Star, he was the first rookie to lead the American League in home runs, going on to drive in 100 or more runs for five consecutive years and twice led the league in home runs and twice in runs batted in (RBIs).
