Sri Lanka's teenage spinner Dunith Wellalage has been included in the final 12 for the second Test against Pakistan in Galle, skipper Dimuth Karunaratne said on Saturday. The 19-year-old Wellalage, a left-arm orthodox who awaits his Test debut, seems a likely replacement for injured spinner Maheesh Theekshana as the hosts look to bounce back in the two-match series after their opening loss. "Dunith Wellalage is back in the squad" after being released from the Test squad for a domestic match, Karunaratne told reporters.
