Kieron Pollard
A name generally tagged with destruction and crazy fielding antics in the Mumbai Indians team was literally nobody to the outside world until his performance in the 2009 Champions League T20. Playing for a West Indies league team, Trinidad, and Tobago, he scored a staggering 18-ball-54 against New South Wales to snatch the limelight of the IPL bidders. Next year, he was picked up by Mumbai Indians.
He then slowly emerged as an integral part of the West Indies T20 squad and went on to win the WT20 title in 2012. He also helped MI win the IPL in 2013 and has numerous Man of the Match awards to his name so far.
