Phillip Price and Lee Westwood, two of the surprise heros for last year's winning European Ryder Cup team, will headline the field.
Price, who shocked the world with his upset of then world No. 2 Phil Mickelson, returns to the tournament where he has won both of his career European Tour titles. He first won back in 1994, then followed it up with his second victory two years ago in 2001.
The 36-year-old Welshman will be trying to become only the third player to win the event three times, following Spaniards Angel Miguel (1954, 1956 and 1964) and Ramon Sota (1963, 1969 and 1970).
Westwood, whose still struggling to find the form that made him a world's top-10 player, still hasn't won since the 2000 season. That year he won an outstanding six events. Though his play in the Ryder Cup did show some promise, he has yet to make it happen in a regular season event, making only two cuts this year, his highest finish being a tie for 28th.
With the dearth of superstar talent in Portugal, it gives many of the up-and-coming players a chance to break out and capture their first career title.
Several players who won on tour last year are in the field this week, including Robert Karlsson, Bradley Dredge and Tobias Dier.
The purse is $1,346,042, with the champion receiving $224,300.
