The 21st edition of the Portuguese tournament is to be staged from May 16-19 at Santo da Serra and carries a total prize fund of 675,000 euros ($872,500).
Defending champion Ricardo Santos of Portugal will look to make it a title double next year.
"The fact Ricardo has been named Rookie of the Year will serve to increase the excitement as we look forward to next year's renewal," the tour's chief operating officer Keith Waters said in a statement on Tuesday.
