Rory McIlroy leads the betting market ahead of the tournament in Valhalla, hoping to make it back-to-back majors.
At 5/1, McIlroy will look to add to his other big victories recently - in the open championship at Hoylake and the WGC- Bridgestone invitational. But are there other options to look at in the market? We've got a few players on our radar...
What Need To Know
Valhalla is a 71-par Jack Nicklaus designed course. Located south of Louisville, it is a total of 7,458 yards. After hosting the 2008 Ryder Cup, the course underwent renovation in 2011/2012, expect it to be in pristine condition for this week.
13 of the past 15 winners have won tournaments earlier in the year. An omen that should encourage McIlroy. Furthermore, half of the past 14 winners won the PGA with double digit under pars. Expect humidity in Kentucky and a 30% chance of thunderstorms to boot.
After kicking his missus to the kerb, it's been rainbows and sunshine for the Northern-Irishman. He's putting better than ever before recently and is finding the green consistently too. He won the PGA in 2012 as well as finishing third in 2009 and 2010 respectively.
Adam Scott 12/1
The current world number two has been in great form too. Of course, after losing the number one spot, Scott will have a point to prove and with eight top ten finishes and a win in the past ten majors, he is always a good bet.
Sergio Garcia & Justin Rose 18/1
Rose was Europe's second top points scorer when the Ryder Cup was played here in 2008, which will breath confidence into the Englishman. Garcia played some great golf at Firestone last week, only to run into McIlroy, who seems unplayable right now.
As the WGC-Bridgestone invitational is always played a week before the PGA, it has acted as a form guide for the US tournament. This contributes to McIlroy's chances, as he won last week and PGA winners have often won previous tournaments in the same year.
