NOT OUT. Simple.
It looks like Stokes puts hand to ball because we know the trajectory of the ball, but in that split second when Starc throws the ball Stokes is defending himself and trying to get back in his crease.
In comparison to Gooch in 1993 - the latter was not in any sense trying to evade the ball but intentionally defending his wicket as the ball came down. In that sense, although Gooch could not be accused of cheating, as it was a split second decision, and he rightly didn't question the appeal and decision.
We often see bowlers hurl (or threaten to hurl) the ball at the stumps. I would expect that when we get the chance we should throw it at Smith's head...
I thought that a country that buried Phillip Hughes after being hit on the back of the head would show some awareness that when a ball is bowled/hurled at someone they tend to put their hands out.
Shame on the Aussies.
