South Africa captain Hashim Amla will not underestimate a Zimbabwean unit nine positions inferior in the International Cricket Council's Test rankings, during this month's one-off fixture at the Harare Sports Club.

The number one-ranked Proteas and minnow Zimbabweans have met seven times in the longest format of the international game. South Africa have won six times, with one draw. Their last fixture was in 2005 in Centurion.

"We haven't been to Zimbabwe in probably one or two years now. For us it will be business as usual. Test cricket and international cricket, you can never let your guard down. It's quite important to keep the winning ways and that's what we intend doing," said Amla.

The tourists have named an unchanged squad on the back of a recent series triumph in Sri Lanka. The uncapped Dane Piedt and Stiaan van Zyl have been retained, while the talented Quinton de Kock will likely remain as wicketkeeper.
