With all the home support to his advantage Oringa capitalized on his good volleys and stamina to battle past the more seasoned Gasigwa.  "This is a very sweet victory and it gives me the guts to even play my heart out to the finals,” Oringa told Xinhua just after the game.It was an intense game with Olinga taking a 5-2 lead in the first set, only for the experienced Gasigwa to fight back and win the set in a tie-break. But Olinga returned determined and hungry to take the second set 6-2. The deciding set which kept spectators on their toes saw long rallies and clever play that Olinga chased at 4-1 and managed to take it to the after tie-break.
