Like a highly skilled tennis player, Frost adhered to the conventions of traditional line and meter, proving his game on the international court by winning four Pulitzer Prizes for Poetry in his lifetime. In the 1947 article 'Those Who Make Poems,' Chicago poet Carl Sandburg challenged the status quo of poetry: 'recently a poet was quoted as saying he would as soon play tennis without a net as to write free verse…The poet without imagination or folly enough to play tennis by serving and returning the ball over an invisible net may see himself as highly disciplined.' 1 The poet he referred to was Robert Frost, a serial practitioner of iambic pentameter.
