Brooks Koepka has retained the US PGA Championship after overcoming a wobble to take his fourth major title.
World number one Dustin Johnson failed to capitalise on a dip in Koepka’s game to finish second.
Koepka, the 2017 and 2018 US Open champion, had a seven-shot lead at the start of the final round but saw that cut to one after four bogeys from the 11th.
However, Johnson dropped shots on the 16th and 17th as Koepka, who carded a four-over 74, won by two on eight under.
England's Matt Wallace tied for third, earning his best finish at a major.
