Dom Sibley’s titanic triple century powered Surrey to a club-record 820 for nine as Durham felt the heat with the Kookaburra ball in the Rothesay County Championship.
Resuming on 169, Sibley, who made the last of his 22 Test appearances for England four years ago, made a career-best 305, with the opener thumping 29 fours and two sixes in a marathon 475-ball innings that ended with Surrey on 745.
