Orr won the event last season in the most spectacular of fashions, as he blistered a 2-iron second shot to the closing par-5 18th hole of the Le Meridien Penina course, and then rolled in the 12-footer for an eagle and a one-shot triumph.
It marked the first victory on tour ' and a much-awaited one at that ' for the Sir Henry Cotton Rookie of the Year recipient in 1993.
The Scot would then go on to claim another trophy in 2000 at the Victor Chandler British Masters.
If he is to defend this year, however, he will have to do so at a different venue. The Quinta lo Lago course will serve as this years host to the event.
Likewise, should Orr repeat, he will have to muster up some better golf than what he has displayed thus far in 2001. He has only competed in three events so far, with his best showing a tie for 17th at the Caltex Singapore Masters.
Some others scheduled to compete are fellow Scots Colin Montgomerie and Paul Lawrie. In addition, emerging young talents Ian Poulter and Hank Kuehne will be in attendance, as will Andrew Coltart, Sam Torrance and Andrew Oldcorn.
They will all be gunning for a total purse of 1,000,000 euro and invaluable Ryder Cup points for the upcoming edition at The Belfry.
