Cape Town: England pulled off a great escape on the final day of the third Test against South Africa, with tail enders earning an unlikely draw in Cape Town.
Once again Onions was in the middle as he combined with Graeme Swann to survive 17 balls to deny the South Africa a victory and maintain England's 1-0 lead in the series with one Test to go.
The result preserves England's 1-0 series lead and with only the fourth Test at the Wanderers next week remaining, the tourists are guaranteed at least a draw.
Chasing a massive target of 466 for an unlikely victory, England finished on 296 for nine after four wickets fell in the last hour.
Earlier, Ian Bell (78) and Paul Collingwood (40) defied South African attack for nearly 56 overs and took England to brink of saftey.
England had reached the last hour of the game with only five wickets down, but with a breakthrough by spinner JP Duminy, the Proteas took four wickets in 11 overs to come close to levelling the series.
But Swann and Onions, who also salvaged a draw for England in similar circumstances in the first Test, defended stoutly to keep out fast bowlers Morkel and Dale Steyn.
