Although that was a slow, conscientious crawl, made necessary by the state of the match, lefthander Karunaratne has a reputation for scoring at a good clip.
Key fast-medium bowler Lasith Malinga is also in the squad, but likely only to figure in the second half as he continues his return from ankle surgery.
It is expected, barring injury, this will be Sri Lanka's squad for the World Cup, which must be named before the New Zealand series starts, which is in Christchurch on January 11.
Sri Lankan squad: Angelo Mathews (c), Tillakaratne Dilshan, Kumar Sangakkara, Mahela Jayawardene, Lahiru Thirimanne, Dinesh Chandimal, Dimuth Karunaratne, Jeevan Mendis, Thisara Perera, Suranga Lakmal, Lasith Malinga (subject to fitness), Dhammika Prasad, Nuwan Kulasekara, Rangana Herath, Sachithra Senanayake, Shaminda Eranga.
