Walker weighs in on record-breaking pole vault trio
(IAAF News)

Brad Walker, the 2007 world pole vault champion who set the US record of 6.04m in 2008, is a big fan of Armand `Mondo´ Duplantis. But he is glad that the controversial new US mark of 6.05m set by the 19-year-old with joint citizenship in winning last year´s European title for Sweden has been superseded by a man in `the red, white and blue`.
