DALLAS (AFP) – James Hahn fired his second bogey-free 64 of the week on Saturday while Australia’s Jason Day charged into contention entering the final round of the US PGA Byron Nelson tournament.

‘‘I played well out there. Overall it was a good day,’’ said Hahn, the 18-hole co-leader. ‘‘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.’’
Fellow American Billy Horschel was second on 199 after a 66 that included birdies on his last three holes.
Hahn said he won’t worry while sleeping on the lead, even though there were a dozen players within five strokes.
‘‘Tell me what my tee time is tomorrow and I’ll just show up,’’ he said. ‘‘There’s a lot on the line but I feel like when I’m on the golf course there’s a
different animal that comes out and I get very competitive.’’
Day had eight birdies to move into a share of third with second-round leader Jason Kokrak, who shot 72. American Cameron Tringale was fifth at 201 after a 67.
