One of the best finishers of the game, Yuvraj Singh is a treat for Indian cricket fans when on song. His timing, high backlift and power-packed shots make each of his knocks praiseworthy. But as the list of such knocks is a long one, we shortlist his best 12 knocks on. Why 12? Well, it's his birthday and a special one at that. It's 12-12-12 for him.
