Keegan Bradley carded three birdies in his last five holes to take a one-shot lead after the third round of the Travelers Championship. The 2011 PGA Championship winner's nearest challengers are all fellow Americans, one of whom is Rickie Fowler who carded a career-low round but came inches short of joining the exclusive sub-60 club. Bradley had shared the 36-hole lead with Denny McCarthy but by the end of the day Chez Reavie had emerged as his main rival after a second successive 63 lifted him to 20 under. However, Bradley's blemish-free 64 ensured he stayed out in front on another day of low scoring - Patrick Cantlay moved into third place on 16 under with a 61 - where Fowler was the centre of attention.
