The 2015 PGA Championship was the 97th edition of one of golf's most prestigious events. The tournament will took place at Whistling Straits on the Straits Course in Kohler, Wisconsin and was the third time the PGA Championship had been hosted at the venue. Interestingly, the previous tournaments held at Whistling Straits in 2004 and 2010 were both won in play-offs, but there was no such drama this time around despite some top quality golf in the 2015 PGA Championship.Preceded by the Masters, Open Championship and US Open, the 2015 PGA Championship is the fourth and final golf major of the calander year and teed-off on August 13th, running until August 16th. As a major, the very best golfers in the world were be in attendance, each hoping to get their name on the roll of honour which includes some of the sport's all-time greats such as Jack Nicklaus, Gary Player and Tiger Woods. And it's not just a place in the history books on offer, the PGA Championship is the most lucritive of the four majors with an estimated purse of $10 million making it a big pay-day for those finishing the weekend with a low scorecard.Defending ChampionRory McIlroy was the defending champion after his success at Valhalla Golf Club in 2014 gave him a secong PGA Championship victory. McIlroy finished one stroke ahead of Phil Micklelson to clinch his fourth career major title. The Ulsterman however, was not the man to beat again in 2015 as Jordan Spieth had already clinched tow majors heading into the tournament.2015 PGA Championship Is Jason's DayWith success in the 2015 PGA Championship, Jason Day won his first major championship title with a total score of 268 for 20-under - the lowest score in relation to par ever recorded in a major. Jordan Spieth was three strokes behind after a fine effort that could have won the tournament on another occasion and at least had reason te celebrate as he finally surpassed Rory McIlroy as number one in the Official World Golf Ranking.Thunderstorms regularly interrupted play and heading into the final round it was Jordan Spieth looking to join Woods and Ben Hogan with three major victories in a year, but the young American could never get on terms. Branden Grace and Justin Rose also got to within two shots of the lead but fell from contention after double bogeys at the 10th and 13th, respectively and Jason Day held his nerve to record one of the all-time great PGA Championship victories.Jordan Spieth and Rory McIlroy remain ahead of Day in the betting for next year's tournament, but any form over the season could see those prices change dramatically and you should follow us on Twitter to get the latest enhanced odds offers, betting tips and money back specials for all golf tournaments.
