Pakistan declared their first innings for 765 for 6, 121 runs ahead of Sri Lanka's total and the visitors made 144 for five from 31 overs in their second essay on the fifth and final day at the National Stadium in Karachi.

The result of the match on the flattest of pitches was a foregone conclusion and the only interest left on the final day was whether captain Younus Khan would get past legendary Pakistani Hanif Mohammad's 337 or West Indian Brian Lara's world record highest innings score of 400 not out.

But Younis' dismissal early in the morning with the addition of just seven runs to his overnight 306 left almost nothing at stake before Akmal's entertaining innings.

Akmal and Yasir Arafat (50) added another 169 for the unbroken six wicket in 38.3 overs before Pakistan declared their innings in reply to Sri Lanka's 644 for seven declared.

Younis, who became the only third Pakistani to hit a triple century, not only failed to get past Hanif Mohammad's record but also fall short of Inzamam-ul-Haq's 329.
