2015 US PGA Championship
The 97h US PGA Championship was held at Whistling Straits in Wisconsin, with the course hosting the third major of the year for a third time after also hosting in 2004 and 2010. Jason Day had been in fine form going into the tournament and had been well backed by punters, with the Australian duly obliging by winning his first major.
As he had done at the US Open, Dustin Johnson made a flying start to another major as he went round in 66 to finish the day at the head of the leaderboard, with Sweden's David Lingmerth just one shot back and Jason Day was part of a group of eight who were two shots off the lead.
Play was suspended due to thunderstorms on Day Two but Day managed to get his round in and he closed just two shots behind clubhouse leader and fellow Australian Matt Jones.
The rest of the second rounds were completed on Saturday morning before Day continued his march towards the top of the leaderboard. The Australian ended the day two shots clear of the rest of the field and it was the third major in a row that he had at least carried a share of the lead going into the final day - the first man to achieve such a feat since Phil Mickelson in 2006.
Day then romped to victory on the final day as he made a final round 67 to finish three shots clear of Jordan Spieth. In finishing 20-under-par, Day beat the previous major scoring record set by Tiger Woods at the 2000 Open Championship.
