Sri Lanka have dominated Pakistan on the fourth day of the third Test between the two sides at Abu Dhabi, having lost just one wicket in the entire day.
Picking up play on 186-4, batting pair Angelo Mathews and Dinesh Chandimal guided the visitors through the first session unscathed and then beyond 300 before the latter was dismissed on 89.
Prasanna Jayawardene joined Mathews at the crease and the pair managed to see out the rest of the day with their wickets intact, before bad light stopped play with Sri Lanka on 420-5.
Mathews reached his century in the final session, finishing the day on 116, while Jayawardene must wait until day five to get to 50 as he ended two short.
Sri Lanka will begin the final day with a lead of 241.
