At the conclusion of the SA v Aus series in Aus last year I thought Duminy an absolute star had arrived. Not only due to the runs he scored in that series, but the matter in which he scored them. He looked composed at the crease, seemed to have loads of time & appeared to be mature beyond his years. I haven't seen much of him since aside from the odd really bad stream on some crappy site.
What's happened since? Was it a case of him just suiting Australian-like pitches? Has he been exposed against spin? Has there been some technical issue exposed or is it merely a case of bad luck & bad form?
