Five times in 13 games of Cricket World Cup 2019 the ball has hit the stumps only for the electronic 'zing' bails to light up but stay firmly in place.
The latest incident of the bails not being dislodged came when Australia opener David Warner edged India seamer Jasprit Bumrah onto his leg-stump at the Oval on Sunday.
Zings International director David Ligertwood says the company is monitoring the situation. “The Zing wicket system has operated in well over a thousand games. The recent cluster (of incidents) has us stumped," said Ligertwood.
The bails have been in use since 2012. They were used at the 2015 World Cup and have been regular fixtures in the Indian Premier League and Australia's Big Bash League. Zing was looking at whether practical modifications were possible, said Ligertwood, co-developer of the wicket system.
"The issue isn't about the weight of the bails, as a complicated interdependent range of factors come into play.
The bails, stumps, stump grooves, pitch conditions, stump cam, etc,” he said.
The ICC, meanwhile, has made it clear it will not review the use of the zing bails. These perform exactly as regular ones and, in fact, are lighter than those used by umpires when it is windy,” a spokesperson said.
