1. Tilakratne Dilshan:

After starting his career with a bang by scoring an unbeaten 163 against Zimbabwe in his first series in November 1999, Dilshan’s careerdid not take off until he switched his batting position to become one of the most destructive openers in the modern era. Dilshan began Tests as a middle-order batsman but then started to open the innings from 2009. The move paid immediate dividends, as he hit six hundreds and scored 1327 runs at an average of 64.52, in the year.
Post the promotion as a regular opener in all the three formats in 2009, Dilshan had a career defining moment during that year. He scored an astonishing 11 centuries in all the formats in that year, and was named as ICC T20 player of the series in the 2009 World T20 for being the top scorer of the tournament.
