DURBAN - South Africa have reacted to David Warner's comments about their tactics for extracting reverse swing in Port Elizabeth by calling them "sour grapes" and the coach Russell Domingo will use them as extra motivation.

In a radio interview, Warner raised questions about how South Africa managed to find considerably more reverse than Australia during the second Test - the most stark example being Dale Steyn's memorable spell on the fourth afternoon - and suggested they will be making the umpires more aware of anything they feel is untoward.

Domingo said: "It's always disappointing to hear comments like that. We are a very motivated team and this has probably added 10% to our motivation levels to show David Warner and the Australians that we don't play our cricket like that. We pride ourselves on playing cricket honestly. It's not a nice comment to make. It's not nice when one team accuses another of whatever."

Earlier, the South Africa team manager Mohammad Moosejee told the Cape Times: "David Warner's remarks are disappointing and discouraging. It takes the gloss off a great Proteas team performance. It smacks of sour grapes and it could just be a tactical plan to get us involved in matters that will distract our attention from this crucial Test in Cape Town."

Moosajee then took at dig at Warner by adding: "Hardly anyone takes anything David Warner says seriously anyway." Warner has been in impressive form during this series with 263 runs in four innings although has benefited from some poor catching by the South Africans.

He and Chris Rogers added 126 for the first wicket in Australia's Port Elizabeth chase, but Warner's dismissal to JP Duminy gave South Africa their opening and they stormed through it during the final session as they claimed nine wickets to level the series.
