A left-handed batsman who adopts a crab-like stance and slow bowler, Yardy shot to prominence in 2005 with a an outstanding campaign for Sussex.
Up until that point, the all-rounder had only shown flashes of promise with the bat, epitomised by him hitting just one century in his first 38 four-day games.
That he scored five in the 2005 season alone illustrated his improvement; Yardy struck a total of 1,520 first-class runs that season.
More impressive performances in all forms of the game the following season caught the eye of the England selectors, with Yardy making his international debut in the one-day international series against Pakistan.
He took 3-24 at Trent Bridge on debut, helping England to their first ODI win of the summer, and also contributed a stunning catch in the outfield.
Those performances earned Yardy a place in England’s 14-man squad for the International Cricket Council Champions Trophy.
But, batting at number three, the left-hander struggled to impress and did not feature on the international scene again for just under four years.
In the meantime, he did frequently skipper England A and, in 2007, he was Sussex’s vice-captain as they claimed their second successive LV= County Championship title.
When Yardy did return to the international fold, for the ICC World Twenty in 2010, he did so in style, playing every match of England’s historic triumph.
He was a regular member of the limited-overs teams for the remainder of that year and into 2011, earning him a place in England's World Cup squad.
Having played in three of their first four group games, Yardy returned home early suffering from depression. He subsequently missed the opening month of the domestic season but returned to lead Sussex in early May.
Yardy enjoyed a fine season in the championship, hitting 617 runs at an average of 44.07 as Sussex consolidated their place in Division One having gained promotion the previous year.
