4. Mark Boucher:
At number four in the list of Fastest 15 Centuries in ODI is former South Africa keeper-batsman Mark Boucher for his 44-ball ton against Zimbabwe in 2006. It was a great display of minnow bashing as Boucher tore away the Zimbabwe attack and etched his name into the record books with his solitary ODI century.
He came in to bat at the number and made the most of his promotion by slamming a whirlwind century. He ended up scoring 147 runs in 68 balls and hit 8 fours and 10 sixes.
