Kohler (United States) (AFP) - Jordan Spieth stepped up his bid for golf history at the PGA Championship on Friday, firing a second-round 67 that moved him within one stroke of David Lingmerth's clubhouse lead.
Sweden's Lingmerth had eight birdies, four bogeys and a double-bogey in a roller-coaster of a two-under par 70.
Lingmerth got as low as eight-under, and his 36-hole total of seven-under 137 gave him the outright lead with Dustin Johnson, the overnight leader on six-under, about to tee off.
