Jason Day says he played 'hardest round of golf' in US PGA win

Australian Jason Day says securing his first major title win "was probably the hardest round" he has ever had to play, as he finished with a record score of 20 under par at the US PGA Championship.

The world number five saw off a chasing pack that included Masters and US Open champion Jordan Spieth, who finished three shots back in second place and now moves up to number one in the new world rankings. 

South African Branden Grace was third on 15 under and Justin Rose of England finished fourth on 14 under after his challenge faded with a double bogey on the 13th.
