U.S. Open and "win it", and he did exactly that. Hagen was also very skilled at baseball, primarily as a pitcher and shortstop. He canceled a 1914 tryout for the Philadelphia Phillies in order to play in a golf tournament. Later that week, Hagen was the U.S. Open Champion, and his career was changed forever. Raises stature of golf professionals Hagen was a key figure in the development of professional golf. He emerged in an era when the division between amateurs and professionals was often stark, with the amateurs having the upper hand in some sports, golf among them. This was especially true in Great Britain, the leading country in competitive golf when Hagen began his career.
