Pakistan captain Misbah-ul Haq won the toss and elected to bat in the first Test against Sri Lanka in Galle on Wednesday.
The start was delayed by 30 minutes due to a wet outfield caused by overnight rain. Bad weather has been forecast on all five days of the Test.
Both teams went in with two spinners -- Saeed Ajmal and Abdur Rehman for Pakistan, and Rangana Herath and Dilruwan Perera for the hosts -- on a grassless pitch expected to take turn later in the match.
The two-Test series is the final one for former Sri Lankan captain Mahela Jayawardene, who will retire from the longer format after the second Test in Colombo next week.
Sri Lanka: Angelo Mathews (capt), Kaushal Silva, Upul Tharanga, Kumar Sangakkara, Mahela Jayawardene, Kithuruwan Vithanage, Niroshan Dickwella, Rangana Herath, Dilruwan Perera, Shaminda Eranga, Dhammika Prasad.
