Headlining the field is the Barclays-sponsored and world number two golfer, Phil Mickelson.
Mickelson tees off knowing that finishing first or second would see him become world number one, overtaking Tiger Woods, who has held the top spot for the past five years.
The tournament which concludes on Sunday, 11 July will also feature numerous 'major' winners, including Retief Goosen, Vijay Singh, John Daly, Trevor Immelman, Paul Lawrie, Tom Lehman as well as 2008 Barclays Scottish Open winner and newly-crowned US Open Champion Graeme McDowell.
Since its inception in 1986 and its move to Loch Lomond in 1996, the Barclays Scottish Open has developed into one of the most prestigious and popular events on The European Tour.
This year, top 50 ranked world golfers from each of the five continents are represented, underlining the true international appeal of the Barclays Scottish Open.
