Wiaan Mulder has suitably taken the last catch for South Africa to hand Zimbabwe its heaviest innings defeat in 20 years and clean sweep their two-test series in Bulawayo.

South Africa completed an innings and 236-run victory over hosts Zimbabwe on the third day of the second test on Tuesday to convincingly sweep the two-match series at Queens Sports Club.

Chris Gayle questioned Wiaan Mulder's bold declaration at 367*, arguing he missed a once-in-a-lifetime shot at Brian Lara's Test record. While South Africa won, Gayle insists greatness comes from chasing iconic milestones when they appear.
