This is the 98th playing of the PGA Championship, where Jason Day enters as the reigning champion. Day, ranked No. 1 in the world for 22 weeks now, secured his first major championship at the 2015 PGA Championship at Whistling Straits in Wisconsin. He has won seven of his past 22 tournaments.
He set the major championship scoring record for the time being at 20-under 268, breaking the previous record set by Tiger Woods at the 2000 Open Championship. After a final round five-under 67, Day had edged out Jordan Spieth by three strokes and secured his place in PGA Championship history.
This year, the final major moves to Baltusrol Golf Club in Springfield, New Jersey, where a major will be held for the ninth time. This is the second time the course has hosted the year's last major, last hosted in 2005 when Phil Mickelson won his first PGA Championship.
This year's PGA Championship has been moved ahead two weeks in favor of the 2016 Olympics, which golf will be a part of for the first time since 1904. The John Deere Classic, where Jordan Spieth is the defending champion but will not be playing, will take its place on the schedule for any players who did not qualify for the Olympics.
Rory McIlroy, a two-time winner of the PGA Championship, is looking for his second win of the year and fifth career major championship. Having dropped to No. 4 in the world, a win here would be a momentum shifter for McIlroy.
23-year-old Jordan Spieth comes into Baltusrol looking for his third victory of the year, and first major win of the year after winning two of them in 2015. He finished in sole possession of second place at the 2015 PGA Championship.
Dustin Johnson has won two of his last four starts, including his first major win at the U.S. Open. He finished tied for seventh at Whistling Straits last year, and has a chance to finish in the top 10 in each 2016 major with a good performance at Baltusrol.
Other notable players participating in this year's PGA Championship include Rickie Fowler, still looking for his first major win after only making the cut in one other major this year. Adam Scott is looking to catch fire again after winning two consecutive events earlier in the year. Andrew "Beef" Johnston will return to raucous chants from the crowd after a sixth place finish at the British Open.
