Number of batsmen to score 150 or more in a Test innings against Australia at an younger age than Mendis' 21 years and 177 days. Graeme Pollock scored 175, at the age of 19 years and 331 days, at the Adelaide Oval in 1963-64 is the youngest to score 150-plus against Australia.
Number of Sri Lanka batsman who scored a Test century against Australia at a younger age than Kusal Mendis. The previous youngest was Romesh Kaluwitharana who hit unbeaten 132 at the age of 22 years and 267 days in Colombo (SSC) in 1992.
The previous highest score by a Sri Lanka in home Tests against Australia, which was by Asanka Gurusinha in Colombo (SSC) in 1992. Mendis beat that score and his score of 169*, at the end of the third day, is 23 runs short of Kumar Sangakkara's 192 which is the highest for Sri Lanka against Australia. Mendis' score is so far the second-highest maiden century for a Sri Lanka batsman; Brendon Kuruppu's unbeaten 201 is the highest.
The last time a Sri Lanka batsman younger than Mendis scored a Test century - Upul Tharanga made 165 at the age of 21 years and 34 days against Bangladesh in Bogra. Mendis' unbeaten 167 (at the end of the third day) is the second-highest by a Sri Lanka batsman ageing 21 or less. This was only Mendis' second century in first-class career of 24 matches.

Among Australia bowlers only Peter Siddle (58 Tests) took more matches to complete 200 wickets than Lyon who took 55 Tests.

This was the first such instance for Sri Lanka and sixth for any team.
