Dennis Amiss is the first player in ODI cricket to have scored a century on both his debut and in his last match, the only other being Desmond Haynes. On 7 June 1975 at Lord's in the first match of the Prudential World Cup (which was also the very first Cricket World Cup to have been held) Amiss smashed 137 runs in just 147 balls against India powered by 18 boundaries. His innings provided enough leverage for England to post a very imposing and improbable target of 335 for India to be chased down within a span of 60 overs. It was also the first time that a team would score 300 or more runs in an ODI match. The match also featured the infamous and notorious ODI innings of Sunil Gavaskar who in reply to the nearly unreachable target set by England scored an unbeaten 36 in 174 balls with just one boundary to adorn his innings (Is this relevant?).
