Rory McIlroy joined by major winners at USPGA Championship

This year’s USPGA Championship will see the top 100 players in the rankings line-up alongside one another, including the headline group of 2014 major winners - Bubba Watson, Martin Kaymer and Rory McIlroy.

As is tradition at the USPGA Championship, played this year at Valhalla Golf Club in Louisville, Kentucky, the three major winners of 2014 will play together for the first two rounds.

The trio will make up a field set to feature 29 major champions in total, including Phil Mickelson, Tiger Woods, Justin Rose, Adam Scott, and last year's winner of the Wanamaker Trophy, Jason Dufner.

In recent years both Padraig Harrington (2008) and Tiger Woods (2000 and 2006) have won the USPGA Championship when paired in the major winner's group.

Watson, Kaymer and McIlroy will all be looking to add their names to that list, especially the American, who is the only one of the three to have not previously won the USPGA Championship.

Of the trio, McIlroy (7/1) is by far the favourite to claim the trophy, with Kaymer (25/1) and Watson (28/1) similarly fancied by the bookies.
