Gastão Elias needed an hour and 53 minutes on Italian dirt to eliminate Orlando Luz, 23, who ranks 328th in the world hierarchy, 6-4 and 7-6 (9-7), from the tournament in category 80 of the ATP Challenge Tour.
After a balanced and calm opening set with only one break in service in the last game, Gastão Elias wasted a ‘match point’ in the 10th game of the second game and was forced to save two ‘set points’ in the ‘tie- break’ to seal the triumph.
In the quarter-finals, the champion of the Open de Oeiras IV will face the winner of the match between Italian Raul Brancaccio (336th ATP) and Croatian Duje Ajdukovic (297th ATP).
