'Spieth will never be as big as Woods or Mickelson'

USA Today's Christine Brennan says Jordan Spieth's profile in his home country will never eclipse that of fellow Americans Tiger Woods or Phil Mickelson.

World number two Spieth is looking to become the first man to win back-to-back Masters titles since Woods in 2001 and 2002.

But Brennan does not think the Texan, 22, seeks the limelight in the same way as the four-time Augusta champion.
