The first-ever ODI hundred was scored in the second ODI

ODI cricket's first-ever hundred was scored by England's Dennis Amiss in the second ODI against Australia in August 1972, a year after the first-ever ODI. Amiss, born on April 7, 1943, scored the hundred off 130 balls in what was his debut match. He also shared the first-ever ODI hundred partnership, adding 125 runs with Keith Fletcher in the match.
