Why Jonny Bairstow was ruled out in pivotal Ashes moment (VIDEO)

London: Jonny Bairstow was run out by Alex Carey in the first session on day five of the Lord's Test when wandering outside the crease after leaving a delivery.

The incident occurred in the 52nd over of the England innings with Bairstow and Ben Stokes rebuilding for England after the dismissal of Ben Duckett.

Bairstow left the final ball of Cameron Green's over alone to the wicketkeeper and started walking outside the crease assuming the ball was dead. However, an alert Carey realised there was an opportunity to run the batsman out and effected a directed hit at the striker's end to catch Bairstow well short.

In what could be a defining moment in the series, Bairstow was left fuming as the Aussies celebrated around him.

According to law 20.1.2 of the MCC's Laws of Cricket, "the ball shall be considered to be dead when it is clear to the bowler’s end umpire that the fielding side and both batsmen at the wicket have ceased to regard it as in play."

Carey, having watched Bairstow make it a habit of walking outside the crease early, used the chance to run the batsman out.

In this case, the fielding side clearly considered the ball to still be in play and hence it wasn't a dead ball.

The dismissal left England's skipper with Stuart Broad and the rest of the tail with 178 runs to chase down. (UNI)
