6) Zimbabwe – Lost 367 ODIs
Since their ODI introduction in 1983, Zimbabwe grew up in international cricket very well. During 1990-2000, Zimbabwe became the giant killer in ODI cricket due to having many talented players in the squad. However, their cricket has faced a massive fall down since the early 21st century, and their continuous financial crisis has made it more difficult to progress in cricket. After playing over 500 ODIs, Zimbabwe has suffered 367 ODI defeats.
