India's Dipika Pallikal notched up one of the best wins of her career today outplaying fourth seeded Alison Waters of England in five games to enter the quarterfinals of the US Open squash in Philadelphia. The Indian posted a 9-11, 11-5, 3-11, 11-1, 11-6 victory over her English rival.However, another Indian, Joshna Chinappa had little answer to the brilliance of hard-hitting Egyptian Omneya Abdel Kawy, the sixth seed. The Egyptian won 12-10, 11-6, 11-5. With this win, Kawy ensured that the two Indians did not meet in the next round. It will be Kawy, who will now play Dipika in the last eight.
