Bangladesh deny robbing South Africa's Herschelle Gibbs of a world record on Sunday by bowling a wide in the dying moments of the match.
South Africa scored 155 without loss in reply to Bangladesh's 154 for nine to clinch the three-match one-day series with one game to play.
But Gibbs was stranded on 97 not out at the end, just short of becoming the first player to make four consecutive centuries in limited-overs internationals.
The scores were tied with Gibbs on 96, when leg spinner Alok Kapali sent a wide delivery down the leg-side, which ran to the boundary.
Bangladesh captain Khaled Mashud, the wicket-keeper who missed the delivery, denied the wide had been bowled on purpose, explaining that he had told Kapali to bowl down the leg side.
"Herschelle was coming down the wicket, and we felt there was a chance of a stumping.
"He bowled it a bit too quick and a bit too wide, but it was not intentional."
South Africa have played down suggestions that Lance Klusener has been dropped for the final one-day international against Bangladesh.
Klusener has struggled with the bat so far this season, with a top score of 39 not out against Sri Lanka during the Morocco Cup in Tangiers.
He made just nine runs in the first match of the series in Potchefstroom, which South Africa won by 168 runs, but did not bat in Sunday's 10-wicket win in Benoni.
"Lance is being rested, not dropped," convenor of selectors Omar Henry said.
"He's a valuable player and he knows where he stands with us. We're just looking at other options within the squad context."
