Keegan Bradley continues to lead the Byron Nelson Championship, one shot clear of Sang-Moon Bae with one round remaining in Texas. American Bradley has topped the leaderboard for all three days of the PGA Tour event, having opened with a course-record 10-under-par 60. Nathan Green (ninth) remains the best placed Australian after shooting a third-round 68. He posted a two-under 70 for his third round at the TPC Four Seasons Resort in Irving on Saturday, to reach 13-under overall. Having made three bogeys and four birdies to be one under for his round on Friday, it was another inconsistent effort from Bradley, with five impressive birdies undermined by three bogeys – two in succession at five and six and another at 18. The 26-year-old has fond memories of the tournament – he won his first PGA Tour title at the 2011 edition of the Byron Nelson Championship, beating Ryan Palmer in a playoff. Bradley&aposs nearest challenger this year is South Korean Bae, who produced a four-under 66 to move to 12 under, outright second ahead of Sunday&aposs deciding round. Americans Tom Gillis and Scott Piercy are third and fourth, 11 under and 10 under respectively, and both have a realistic chance of catching Bradley on the final day. Less likely to mount a challenge are the group of four players tied for fifth at eight under, with American trio Gary Woodland, Harris English and John Huh, as well as South African Charl Schwartzel, all five shots off the pace.
