2 Previous instances of two Bangladesh batsmen making a 50-plus score in an innings against South Africa - in Chittagong, 2003 and Centurion, 2008. Tamim (57) and Mahmudullah (67) did so in this match, but Bangladesh have never had three half-century scores in an innings against South Africa.
89 The partnership between Tamim and Mahmudullah, the highest third-wicket stand - and the second highest for any wicket - for Bangladesh against South Africa. Habibul Bashar and Javed Omar had added 131 for the second wicket, also in Chittagong, in 2003.
5 Number of partnerships among Bangladesh's top-ten stands against South Africa that have come in Chittagong. Bangladesh have posted 17 stands of 50 or more against South Africa, and seven of those in Chittagong.
1 Number of times Bangladesh have taken a first-innings lead in eight Tests against South Africa - in Dhaka, in 2008. They are 69 behind South Africa with six wickets remaining in the first innings at the moment.
46 The stand between Tamim and Imrul, Bangladesh's joint second best opening partnership against South Africa. The only time Bangladesh's openers posted a 50-plus stand against South Africa was when Al Sahariar and Hannan Sarkar had a 52-run partnership in Potchefstroom in 2002.
13 Overs bowled by Dale Steyn without taking a wicket. He has never bowled 10 or more overs previously against Bangladesh without taking a wicket. He had gone wicketless against Bangladesh in Centurion in 2008, when he bowled only eight overs in the innings.
