Having long broken records for fun in the longer format of the game, Sam came to the fore in white-ball cricket last season, establishing himself at the heart of the Bears batting plans in the shorter formats.
The first sign of what was to come arrived in 2016 pre-season in Dubai when he blasted 85 runs from just 57 balls against world champions West Indies. That proved that Sam's precocious talents can tower in all formats and he went on to form, along with Ian Bell, the classiest opening pair in the NatWestT20Blast last year.
Brought up in Australia but now England-qualified, Sam is already in the national selectors' thoughts as he was selected for the North v South 50-over series in the UAE this spring. He has a phenomenal appetite for batting and run-scoring and, in T20, an ability to judge a match situation and pace an innings which belies his young age.
