Played on the famed Tom Weiskopf-designed course, a virtual who's who of international golf is set to tee it up with hopes of joining an impressive list of past winners at this event.
Several Hall of Famers, a gaggle of major champions, multiple Order of Merit winners, and a slew of top notch up and comers are here to try to dethrone the defending champion and world No. 2 Ernie Els, who cruised to the title in 2003.
Standing in his way for a repeat will be current Masters champion Phil Mickelson who seems to have just about everything firing on all cylinders.
Mickelson not only leads the PGA Tour in top 10s with 11 in 15 starts, including two wins and a pair of runner-up finishes, he more importantly captured his first major championship at this years Masters. Outlasting Els with an incredible back nine at Augusta, Mickelson then backed it up at the second major of the year with a strong second place showing against Retief Goosen.
Goosen withdrew from this week's event after winning the Smurfit European Open over the weekend, opting to take a week off before next week's Open Championship.
Els, meanwhile, is also putting together quite a 2004 season himself with one win each on the European Tour and the PGA Tour. He defended his title at the Sony Open in January and then won his third consecutive Heineken Classic in Melbourne, Australia.
Els has finished inside the top 10 in each of his seven starts this year on the European Tour schedule, and along with his win, has four top five finishes.
Other former past champions at Loch Lomond in the field are Jesper Parnevik (1993), Thomas Bjrn (1996), Tom Lehman (1997), Lee Westwood (1998), Colin Montgomerie (1999) and Eduardo Romero (2002).
Reigning British Open champion Ben Curtis has also made his way across the pond to get ready for his title defense at the Open Championship at Royal Troon.
Rounding out the field for this star-studding event will be Darren Clarke, Lee Westwood, Paul Casey, Ian Poulter, Colin Montgomerie, Miguel Angel Jimenez and Jose Maria Olazabal.
