Michael Cohen led a strong bowling display by the South Africa Emerging team before Senuran Muthusamy and Thomas Kaber shone with the bat to leave Zimbabwe A on the ropes after day three of their second four-day match in Kwekwe on Friday.
Cohen first claimed three for 66 to help bowl out the hosts for 225, before the tourists replied with 214/5 declared at the Sports Club.
That left the Zimbabweans with a victory target of 444 and they managed to reach stumps on 30/0.
Apart from Cohen, there were also notable performances from Lwandiswa Zuma (2/42), Okuhle Cele (2/36) and Kyle Simmonds (2/33) – leaving the home side shot out in 64 overs.
The South Africans then scored at a brisk 4.28 to the over to move the game forward rapidly. Central to their cause was Muthusamy, who followed his first-innings 102 with 85 (93 balls, 8 fours). Kaber also impressed with an unbeaten 55 (68 balls, 5 fours, 1 six) and so too did Isaac Digale (47).
That left Zimbabwe, who trail the two-match series 1-0, with a massive task on their hands, but they managed to negotiate nine tricky overs before the close thanks to captain Chamu Chibhabha (23) and Brian Chari (7).
