Ball tracking shows that indeed was umpire's call on leg stump so Jonny Bairstow would not have overturned it had he reviewed.

Bairstow is struck halfway up the pad, massive appeal and given.
Worth a review? Not for YJB as he strides off. Was probably clipping leg stump.

Aadam: Will never get tired of watching Jason Roy hit bowlers all over the park.
Need 100 off 78 balls
Andile Phehlukwayo continues to take the pace off, forcing Jason Roy and Jonny Bairstow to adjust and try to pick up ones and twos.
But that's so clever from Roy! The England opener walks across his stumps and sweeps it round the corner for four. No fielder there.
That turns a decent over into a very strong one for England - 10 from it.

As I said, YJB is very quick.
Jonny Bairstow is very quick and wants two despite hitting it straight towards deep point.
A very fine throw in by Rassie van der Dussen and Quinton de Kock breaks the stumps.
But Bairstow was home. The umpires want to check anyway.
Andile Phehlukwayo is on.

Alex Adams: Not sure if it’s an unpopular opinion or not but I think Roy is pretty comfortably our best ever white-ball batsman - look at how much we missed him in the World Cup.
