KOHLER, Wisconsin, Aug 16 (Reuters) - Australia's Jason Day held his nerve to end five years of close calls at the majors with an emotional breakthrough victory by three shots over American Jordan Spieth at the PGA Championship on Sunday.
World number five Day, two ahead of Spieth overnight, never relinquished his lead as he closed with a five-under-par 67 on a blustery afternoon of hazy sunshine at Whistling Straits to post a major record low of 20-under 268. (Reporting by Mark Lamport-Stokes; Editing by Andrew Both)
