Interesting what people make of Azhar Ali, and he currently doesn't appear to have that style to really catch the eye but after 24 Tests to be averaging 45 shows he's certainly been effective in the early part of his career. Always thought he was younger than what he is, don't know why but had the impression he was a real youngster when handed his debut, but he was 25.
From what I've witnessed so far, he's refreshing for this Pakistan side in so much as the discipline he shows when batting, he has demonstrated his capabilities of playing shots all round the wicket, but he doesn't get carried away and try too hard to catch the eye by playing a multitude of strokes in one innings. As people have already said in this thread, his patience is an undoubted strength of his, especially with the stroke makers all round him in the Pakistan line-up.
Already he has made two scores in excess of 150, and while they took plenty of time to reach, he didn't give it away, but so far his four tons have come on rather docile sub-continental wickets, I'm sure as his experience at this level and other conditions grows he will become a more accomplished batsman on trickier surfaces, judging by a decent looking technique that he has adopted.
A tough batsman to remove in the right conditions, but certainly still a work in progress outside his more comfortable conditions, but promising signs imo.
