Ricky Ponting – 98* vs New Zealand
No player has scored a century on T20I debut but Ponting came closest of anyone, in the very first match of the format. Coming in at No.4, the Australian batsman compiled an exquisite 55-ball 98 as he helped his side register 214/5 in 20 overs and eventually win by 44 runs.
One of the greatest batsman that the game has ever seen still holds this record and it remains to be seen if it is broken anytime soon.
