World number one Rory McIlroy hit a superb seven-under 63 to move within two shots of American leader Harold Varner III at the halfway stage of the PGA Tour’s return event in Texas.
McIlroy holed an eagle and six birdies, with his only bogey coming at the last as he improved to nine under.
Varner III began with a triple bogey but had five birdies in his final six holes in a 66 as he reached 11 under.
Americans Jordan Spieth and Bryson DeChambeau are at 10 under after 65s.
England’s Justin Rose, who shared the overnight lead on seven under with Varner III, birdied the first two holes but his momentum was halted by a bogey on the third.
Further bogeys followed on the 10th and 11th but birdies on the 13th and 18th saw him sign for a 69 and eight under total. (BBC)
