The incident took place on Day 4 of the match, with Ireland sitting on a score of 74/5, looking to chase down the target of 185 runs. It was the second ball of the 18th over when Andy McBrine hit a neat drive on the off-side as the ball raced towards the boundary line, on the bowling of pacer Richard Ngarava.
The ball raced towards the boundary, prompting Zimbabwe's Tendai Chatara to go on a hunt and prevent it from touching the rope just centimetres before the rope.
But, the momentum of the run took the fielder beyond the boundary rope, making it impossible for him to quickly return the ball.
By the time the fielder picked up the ball and threw it back, Andy McBrine and Lorcan Tucker had added 5 runs to the team's total by running between the wickets.
