Dean Elgar and Temba Bavuma hit half-centuries to give South Africa a slight edge on the first day of the first Test against Bangladesh on Thursday. 

South Africa were 233 for four when bad light stopped play after being sent in to bat. South African captain Elgar made 67 in an opening partnership of 113 with fellow left-hander Sarel Erwee (41), but Bangladesh fought back before Bavuma and Kyle Verreynne steadied the innings with an unbeaten fifth wicket partnership of 53.
