I think it's a good move even if he scores 20 odd on average. I believe he'll average more in mid 30's as an opener. I see more opening partnerships of 50 w/ SN and Ash. Against Kenya the duo put up 38 in 6 overs which imo is better than what Rajin or Jo would provide since we'd reach 38 by the 10th over with a wicket down anyway.
12.6 Syed Rasel to Sangakkara, OUT: What a delivery, completely fooled Sangakkara, first five delivery were the outswingers and now, this one comes in sharply, Sangakkara tries to left it and ball hits the off stump, top class bowling!
