  • Mahela Jayawardene and Thilan Samaraweera's partnership of 437 is the highest for the fourth wicket in Tests. It's also only the second 400-plus stand for that wicket in Tests, after Colin Cowdrey and Peter May's 411 against West Indies in Birmingham in 1957.

  • This is the fourth instance of two Sri Lankan batsmen - and the 15th overall in Tests - scoring double-hundreds in a single innings, which is the most by any team. Australia and Pakistan have achieved this on three occasions each. The last time this had happened in Pakistan, Sri Lanka had been at the receiving end, as Qasim Umar and Javed Miandad hammered doubles in Faisalabad in 1985.
  • In 27 innings, Jayawardene and Samaraweera have averaged 68.80 together, which is marginally higher than the 68.59 that Jayawardene and Kumar Sangakkara average. Click here for Jayawardene's average stands with each batsman.
  • Jayawardene scored his fifth double-century, and his first outside Sri Lanka. Only two Sri Lankans - Marvan Atpattu and Sangakkara - have scored more double-hundreds. Click here for the full list of Sri Lankan double-centurions.
  • There were no sixes in the Sri Lankan innings. It's the eleventh time a team has scored 600 or above in an innings without hitting a six.
  • Sohail Khan conceded 131 runs in 21 overs. His figures are the fourth-worst in terms of runs conceded for debutants who've gone wicketless in an innings.
  • In their epic stand, Jayawardene and Samaraweera scored 110 runs behind the point region - 60 of them in boundaries. Most of these runs came on the first day, as Pakistan did not keep a third man.
