KARACHI Davis cupper Jalil Khan had to muster all his skills to overpower promising Adnan Khan in straight sets to qualify for semi-finals of the PSO-sponsored 13th Anti Tobacco Day Tennis here on Thursday afternoon at the cemented courts of Karachi Club. Though the Davis cupper won the match, yet he had to stay on court much longer than expected before winning 6-3, 6-3. Young Adnan Khan knew he had no chance against his stronger opponent but he put up a good fight and in the process won six games from the winner. Jalil Khans elder brother Aqeel Khan and his younger brother Yasir Khan also moved to the last four stage of the event. Top seed and favourite Aqeel Khan beat Omer Shahid 6-1, 6-3 and Yasir Khan defeated Danish Ahmed 6-3, 6-0. In ladies quarter-finals, tiny Maheen Dada defeated Dr Shahrukh Khan 6-3, 6-0.

In mens doubles quarter-final, favourite pair of Aqeel Khan and Nomi Qamar beat Mustafa Jamal and Talha Zubair 6-0,6-0. Brothers pair of Jalil Khan and Yasir Khan defeated Muhammad Saeed and Bashir Khan 6-2,6-1.
