Hahn leads at Byron Nelson by one stroke

James Hahn fired his second bogey-free 64 this week to grab a one shot lead heading into the final round of the PGA Tour's Byron Nelson event on Saturday. Hahn has a slim lead over a crowded leaderboard that also includes Australia's Jason Day who blasted a 63 in the third round to move into contention at the TPC Las Colinas course just outside of Dallas. "I played well out there. Overall it was a good day," Hahn said. "It is really close. One putt here or there. You need good breaks to happen to keep the momentum going and I did that today." Hahn is at 12-under-par 198 while fellow American Billy Horschel is one stroke back after a four-under 66 that included making birdie on each of his last three holes. World number three Day had eight birdies to move into a tie for third with second-round leader Jason Kokrak (72). Day and Kokrak are two shots adrift of Hahn at 10-under 200. Cameron Tringale (67) is alone in fifth at 201. Day made an incredible 60 foot birdie putt on the par-three 17 to move into a tie for the lead. Reigning Masters champion Sergio Garcia, of Spain, fired a 64 on Saturday to get to 202 and into a tie for sixth with former Byron Nelson champion Jason Dufner (65) and Bud Cauley (68). The defending champion Garcia shot 29 on the back nine Saturday, the same score he posted on the front nine in the opening round when he won in 2016. Five players, including Scott Brown (65), Scott Piercy (66), Grayson Murray (68), Chad Campbell (68) and An Byeong-Hun of South Korea (69), are at 203 and within striking distance. World No. 1 Dustin Johnson is tied for 19th after carding a one-over 71 Saturday. That snapped a streak of 14 consecutive par-or-better rounds at the Byron Nelson for Johnson who is seven shots behind Hahn.
