England's top seed Adrian Grant and Mansoor Zaman, the No3 seed from Pakistan, will meet in the final of the CNS International after surviving marathon semi-final battles in the $25,000 PSA Tour event at the Roshan Khan/Jahangir Khan Complex in Karachi, Pakistan.

Zaman, currently the highest-ranked player in Pakistan, avenged his shock defeat earlier this month in the World Open in Egypt when he beat teenage compatriot Aamir Atlas Khan.

But the 16-year-old qualifier from Peshawar fought back from a game down against Zaman to lead 2/1.

Left-hander Zaman, the South Asian Games champion, called upon his greater experience to reclaim the advantage - ultimately winning 11-6, 7-11, 7-11, 11-7, 11-10 (2-0) in 64 minutes to reach his 14th PSA Tour final.

Grant also had to come from behind - recovering from the loss of the first game to beat Irishman Liam Kenny, the fourth seed, 9-11, 11-1, 11-6, 11-8 in 77 minutes.

Londoner Grant, one match away from his third PSA title win in Pakistan, is celebrating his 16th PSA final appearance.

Semi-finals:
[1] Adrian Grant (ENG) bt [4] Liam Kenny (IRL) 9-11, 11-1, 11-6, 11-8 (77m)
[3] Mansoor Zaman (PAK) bt [Q] Aamir Atlas Khan (PAK) 11-6, 7-11, 7-11, 11-7, 11-10 (2-0) (64m)
