Galle: Kumar Sangakkara smashed his 10th double century against reckless Pakistan as Sri Lanka declared their first innings at 533 for 9 for an overall lead of 82 runs on the fourth day of the first Test on Saturday.
Pakistan lost opener Khurram Manzoor to left-arm spinner Rangana Herath to finish the day on 4 for 1 - still trailing by 78 runs.
Sangakkara's imperious 221 in just over 11 1/2 hours off 425 balls was studded with 24 fours as the master batsman made Pakistan pay heavily for dropping him of Saturday's very first ball and later on 168.
Abdul Rehman, who missed a first-ball sitter of Sangakkara, had the left-hander finally stumped late in the last session before Pakistan's tough time in the field ended when the declaration came.
Angelo Mathews made a splendid 91 and fell to offspinner Saeed Ajmal (5 for 166), who finished with a late five-wicket haul after taking his first wicket of the Sri Lankan captain in his 47th over.
Sangakkara raised his 200 off 398 balls with 21 fours when he punched Ajmal to point after tea for a single and is now just two behind Don Bradman's all-time record of 12 double centuries.
Pakistan's bowlers got little support from their fielders on a placid wicket as Sangakkara shared three century-stands in home team's solid response to Pakistan's 451.
He crafted 181 runs with Mathews as Pakistan could only get the wicket of Mahela Jayawardene (59) in Junaid Khan's eventful first over with the new ball in the first session.
Sangakkara, 102 overnight, played a loose drive off left-arm fast bowler's first delivery but Rehman dropped a two-handed catch at point after Sri Lanka resumed at 252 for 2.
Jayawardene, playing his last series before retiring after the second Test, was beaten by his first delivery and got an edged boundary through slips off the next ball before falling to Khan's immaculate delivery that jagged back into the batsman.
Sangakkara, who added 120 with opening batsman Kaushal Silva on the third day, shared the second century-stand by putting on 113 runs with Jayawardene before he continued to frustrate Pakistan bowlers in the post-lunch session with Mathews.
Both batsmen waited for the loose deliveries and played some elegant drives on both sides of the wickets to the frustration of Pakistan.
Sangakkara got a second chance in his marathon knock, which began on the second day, when Younis Khan spilled a chance in lone slip just before the offspinner removed Mathews.
Mathews was out for 90s for the third time in Test matches against Pakistan since last Christmas when he misread a doosra and Younis Khan grabbed a low catch to his right.
Ajmal then wrapped up the tailenders but Dilruwan Perera added a rapid 31 before he was stumped and Mathews declared the innings.
