True Andy, it is only one match but I don't think he's ever been technically good enough nor done enough in county cricket to warrant selection. If they want someone to score quickly they'd be better with Jason Roy. Hales ODI place must be under threat also, he's done diddly squat there for a year now...
Watching the ODIs earlier this year, I had similar thoughts - Hales is very much a front-foot thumper, Roy's footwork looks better and he seems happy both front- and back-foot.
Having said that, Roy usually bats well down the order for Surrey in the first class game so his technique might well get found out if thrown in the deep end in test cricket.
If Surrey gave him a long run opening, we'd have a better idea.
