Well i've already outlined the circumstances of which he had to bowl in , no warm up match, hadn't played a four day game since Febuary, was rushed from Trinidad to play at the last minuet, his hands were cold and had to make his debut on a road that "the best spinner in the world" Graeme Swann was unable to take a wicket on, anyone looking at that with open eyes could see it was a tough ask,
As for excuses, well the english media are spewing that out left, right and centre where Bairstow is concerned!!..Bumble even claimed he was the "next Pieterson" yesterday!!
.
Lastly regarding the chance,
he totally fooled Bell and forced an edge straight into Barath's hands but it popped out again, a tough chance but a better fielder would have got that imo.
