Pakistan beat Sri Lanka by eight wickets in the fourth One-Day International on Wednesday in the UAE to clinch the ODI series, which is their seventh One-day series win in the year.
Pakistan had restricted Sri Lanka to 225 all out in 48.5 overs with Ajmal (4-39) and paceman Umar Gul (3-37) sharing the spoils, while Hafeez became the sixth batsman in all One-day cricket to hit three tons in one bilateral series.
After the conclusion of the One-day series, Pakistan and Sri Lanka will play three Tests, starting in Abu Dhabi on December 31.
