Australia have let their displeasure be known after the fourth day of the second Ashes test against England, after fast bowler Mitchell Starc was denied a controversial catch.
Late on day four at Lord's and with England at 113/4 chasing 371 in their second innings, Australia looked to have landed one last blow before stumps, when a Cameron Green short ball was deflected to Starc on the fine leg boundary.
But even as Starc held on to appear to complete the catch, the Australian fast bowler grounded the ball when his left hand hit the turf, seeing third umpire Marais Erasmus rule not out, and give Duckett a life.
And despite protests from the Australians, the decision stood.
Duckett had already began to leave the field of play, before replays at the ground prompted him to stay.
After the conclusion of play, the MCC - the custodians of cricket's laws - issued a statement clarified the laws in support of Erasmus' decision.
"Law 33.3 clearly states that a catch is only completed when the fielder has 'complete control over the ball and his/her own movement,'" the statement said.
"The ball cannot touch the ground before then. In this particular incident, Mitchell Starc was still sliding as the ball rubbed the ground, therefore he was not in control of his movement."
The decision has not gone down well with Australia, though. Speaking on the BBC, Australia great Glenn McGrath hit out against the third umpire.
"I'm sorry, that is the biggest load of rubbish I've ever seen," he said. "He's got that under control, the ball is under control.
"That is a disgrace. I'm sorry, that is a disgrace. I've seen everything now. I cannot believe that. That is ridiculous.
"If that ball is not under control, that is ridiculous."
England will resume on day five at 114/4, still needing another 257 runs for victory, while Australia need six wickets to go 2-0 up in the best of five series.
