There has been a great deal of furore concerning umpiring decisions in the Ashes series so far, much of it entirely justified. But Australia only had themselves to blame on day three at Old Trafford as they failed to review a crucial decision.
Kevin Pietersen was trapped in front of his stumps by Shane Watson, only for captain Michael Clarke to not back his convictions and take the chance to send the England dangerman back to the pavilion.
Pietersen had 62 runs to his name when Watson all-but-dismissed the England batsman, and he went on to frustrate the tourists with his 23rd Test century before he was eventually out for 113.
England were 176-4 at the time and in a pretty precarious situation in response to Australia's formidable 527-7 declared in the first innings, and Clarke would be left to rue his indecision.
When Pietersen was later dismissed, England had 280 runs on the board.
Australia's use of the DRS in this series has been extremely poor and, in not backing their early judgement and having the decision reviewed, they may have squandered their chance of winning the third Test and preventing a third successive Ashes series defeat.
England only require a draw in the match to retain the Ashes, and the hosts may reflect upon Pietersen's reprieve as a key incident as they move towards preventing a defeat in Manchester.
The delivery from Watson pitched around the off stump and trapped Pietersen in-line with the middle stump.
The ball was projected by Hawkeye to go on and hit the leg stump full on.
The result of the whole incident was one of sheer frustration and annoyance from Watson, Clarke and the entire Australian team.
Australia immediately knew that they had made a big mistake as Pietersen smiled broadly at the crease after discovering how fortunate he was, and even coach Darren Lehmann raised his finger on the balcony to indicate that it was out.
Pietersen was, perhaps, unfortunate to depart later on as he was dismissed lbw by left-arm fast bowler Starc after a small mark was visible on the Hotspot technology suggesting an inside edge from his review.
In a Test dogged by controversy over the officials' use of the DRS, third umpire Kumar Dharmasena opted to side with his on-field colleague Tony Hill.
But it is the tourists who have struggled to use the DRS effectively throughout the series with numerous cases of decisions either rashly reviewed or not at all costing them dearly.
Australia's latest failure with the DRS could end up representing the final costly error in terms of their last-ditch attempt to salvage the Ashes after Pietersen's dramatic reprieve.
