Abu Dhabi, U.A.E, Oct 22: Kumar Sangakkara was closing on an eighth test double century by combining with Sri Lanka teammate Prasanna Jayawardene to frustrate Pakistan's victory bid on the fifth and final day of the opening test at the Sheikh Zayed Stadium.
Sri Lanka, clawing back from a first innings deficit of 314, stretched their overnight 298-5 to 364-5 by lunch, a lead of 50.
Sangakkara, resuming on 161, was unbeaten on 185.
Jayawardene, overnight 25, compiled an unbeaten 66.
The pair took their partnership to 131, a sixth wicket record for Sri Lanka against Pakistan, erasing the previous mark of 121 between Aravinda de Silva and Arjuna Ranatunga in Faisalabad in 1985.
Pakistan's bowlers toiled hard but created precious few anxious moments for Sri Lanka in the two-hour session.
To add to their frustration, fast bowler Aizaz Cheema was twice warned for running on the protected area of the pitch by umpire Tony Hill.
