Record lead for Kokrak at AT&T Byron Nelson

Jason Kokrak shot a bogey-free 8-under 62 Friday for a record five-stroke lead after two rounds at the AT&T Byron Nelson, where local favourite Jordan Spieth missed the cut for the first time at the tournament where he made his debut as a 16-yearold high school junior. Kokrak, the 128th-ranked player in the world, matched the Nelson’s 36-hole record at 12 under after his career-best scoring round, and no one has ever had a bigger lead there after two rounds. Billy Horschel was second at 7 under after three consecutive birdies to finish at 65. Dustin Johnson, the world’s No. 1 player, was among six players tied for third. Spieth missed the cut after shooting 75. Nick Taylor of Abbotsford, B.C., had 73 for a 2-over 142. Brad Fritsch of Ottawa and Graham DeLaet of Weyburn, Sask., both missed the cut.
