4. Wahab Riaz (Pakistan):
There was hardly any doubt about the talent of the Pakistani speedster, Wahaz Riaz. But somehow in spite of his blistering pace and reverse swinging credentials, he could never live up to the hype and expectations which he had created for himself. But cometh the Quarter-Finals of the World Cup against Australia, the world witnessed one of the fiercest spells in the history of ODI cricket when Riaz blew away Shane Watson with barrage of bouncers. Since then, there has been no looking back for Wahab as he has transpired to be the pace spearhead of the Pakistani bowling line-up. The left-armer took 32 wickets in 20 matches, this year.
