As part of their process, the third umpire also reviewed to see if the batter was out caught behind.
Smith and Carey deliberately used the ploy on several occasions, meaning Australia got more than their official allotment of three DRS reviews.
Eagle-eyed cricket fans noticed Smith cleverly exploiting the DRS loophole, some arguing it would prompt the ICC to tighten up the rules around DRS and third umpire reviews.
Wisden India’s Abhishek Mukherjee tweeted: “Top thinking by Steve Smith and Australia. Appeal for stumping, they will check for caught behind, and you won’t lose a review.”
Journalist Anand Vasu said: “Rule/protocol change incoming. Australia are completely overdoing the stumping as DRS mechanism. Square-leg umpires are just going to watch stumpings more clearly and not send the decision to the TV umpire.”
Smith’s shenanigans were understandable, given umpiring luck hasn’t exactly been on Australia’s side during the third test.
Mitch Starc had Rohit Sharma out twice in the very first over of the test but the Aussies opted not to review, while Cameron Green was out via a contentious LBW decision in the second innings.
It seemed virtually every LBW call was being sent upstairs to be reviewed as the on-field umpires were mostly reluctant to give it out immediately.
And it seems the new prevailing wisdom is if in doubt, knock the bails off and send it upstairs.
