Third Test, Trent Bridge, day four (stumps): South Africa 362 & 63-5 v England 445 & 118
A tense third Test was left in the balance when bad light stopped play on day four with South Africa 63-5, chasing 202 for victory.
The tourists looked to have snatched the advantage when they bowled England out for just 118.
Shaun Pollock took 6-39 - the best figures by a South African at Trent Bridge.
England's young pace attack bounced back with a superb display, taking five wickets in 21 overs.
But sixth wicket pair Neil McKenzie and Mark Boucher, whose 129-run partnership in the first innings was crucial, soaked up the pressure well.
McKenzie played and missed and bottom-edged regularly on a pitch offering little bounce to reach six not out from 58 deliveries, while Boucher made seven from 27.
Had England - and Flintoff in particular - had an ounce of luck, South Africa would have been in really deep trouble
Already reeling after the loss of Marcus Trescothick first ball on Saturday evening, England were in familiar territory when Michael Vaughan fell in the seventh over of the day.
Vaughan was caught by a diving Boucher off Pollock, leaving his side 17-2.
After first innings centurions Nasser Hussain and Mark Boucher survived an hour of variable bounce and vicious movement from openers Pollock and Makhaya Ntini, a double bowling change brought three quick wickets.
Andrew Hall bowled Butcher through the gate for eight with his first delivery, and had debutant Ed Smith lbw with the very next ball.
Alec Stewart only had time to flick for four through square leg before edging a Jacques Kallis out-swinger.
And Pollock's second spell just after lunch brought the scalps of key men Hussain and Andrew Flintoff.
Hussain was extremely aggrieved to be given out lbw and Flintoff only managed to equal his former captain's 30, including a lofted six off Kallis, before gaining a thick edge to point off an aggressive drive.
If England heads were down, their performance with the ball did not show it.
Opening pair Herschelle Gibbs and Graeme Smith put on 22 in nine overs before the South Africa captain was victim of a dubious lbw appeal to James Kirtley.
But the debutant was far more certain with his dismissal of Jacques Rudolph, also leg before, in his next over.
Steve Harmison battled a calf problem to produce the extra bounce that gained a Gibbs top-edge to mid-on.
And James Anderson built on his first innings five-wicket haul with the wickets of Boeta Dippenaar, caught at midwicket off a tame lob, and Jacques Kallis, who played on off the toe-end of his bat.
Having believed the Test dead, England go into Monday's final day with victory an increasingly strong possibility.
