HARARE (Reuters) - Debutant off-spinner John Nyumbu took five wickets on Zimbabwe's Heroes Day to limit South Africa's first innings total but the hosts still face a tall order after the third day of the one-off test in Harare on Monday.

Zimbabwe reached 28 for one in their second innings, 113 runs behind South Africa’s first innings total of 397, which would have been much higher had it not been for Nyumbu.
