The American golfer Bubba Watson has opened up a three-shot clubhouse lead in the second round of the Masters at Augusta National.
Five straight birdies in his back nine were marred by a bogey on the last hole, Watson - the 2012 Masters champion - finishing with a four under par round of 68, for seven under overall.
Three strokes back is Australia's John Senden, who also shot a 68, while another Queenslander, defending champion Adam Scott, recovered to be a stroke behind in a three-way share of third after a 72.
1992 Masters champion Fred Couples is another shot further back in a four-way tie for sixth.
Three-time former champion Phil Mickelson missed the cut for just the second time in 22 appearances - the big lefty was five over after two rounds.
