Michael Klinger was on the wrong end of a miscount on Sunday as the Perth Scorchers batsman was dismissed off the seventh delivery in an over against Sydney Sixers.
Right-hander Klinger was caught at third man for two by Steve O'Keefe off the bowling of Ben Dwarshuis during the second innings of the Big Bash League fixture in Perth, with on-field umpires Geoff Joshua and Simon Fry checking to make sure the ball had carried to the fielder.
However, the two officials in the middle missed that Dwarshuis had already completed the second over, with the extra delivery proving costly for the Scorchers.
Cricket Australia (CA) confirmed that the ball is deemed to be legal once it has been delivered and therefore the wicket had to stand, though they will assess what happened in a post-match debrief.
A CA statement, which was read out on Fox Sports, said: "It appears there was a miscount of balls in the over and a seventh ball was allowed by umpires.
"As the ball was bowled it is deemed live and consequently the decision stands.
"The incident will be followed up by Cricket Australia’s general match review process and feedback will of course be taken on board."
Scorchers coach Adam Voges described the incident as "not ideal" during an interview with Channel Seven.
"Obviously, it's the umpires' job to count the number of balls in an over," he added.
While Klinger fell in unfortunate circumstances, Perth still went on to surpass Sydney’s total of 177-5 with seven wickets to spare, opener Cameron Bancroft leading the way with an unbeaten 87.
