Add Peng to that. He looked a million dollars when he first broke onto the scene, but he's struggled to make over 20 in an innings over the last 2 years
Hildreth of Somerset looks very good tho, and more importantly he's getting the scores too. Lets hope he carries this on for the rest of the season and into next year.
As for Shafayat he did look good but from the start looked like a great leg side player but hopeless outside off stump, you can forgive a 16yo that but he seems to be still the same even now.
Mutchell of Durham looks good too, bit inconsistent but he does get the occasional good score.
