One Day International

An ODI is decided by the aggregate runs scored by two national teams in separate innings. The side batting first sets a target, and the chasing side wins by reaching it; otherwise, the team with more runs wins, while equal scores produce a tie unless a competition rule provides a further decider.¹

Each innings is limited to 50 six-ball overs, although an innings can end earlier when all but one batter are dismissed, the target is reached, or other conditions apply. Eleven players represent each side, with one team batting and the other fielding at a time. A bowler may usually deliver no more than 10 overs in an innings, encouraging the captain to distribute the workload among several bowlers.²

ODIs are longer than Twenty20 Internationals but substantially shorter than Test matches. Their defined duration makes them suitable for bilateral tours and tournaments while retaining room for changes in momentum, tactical pacing, and sustained batting partnerships.

ODI tactics are shaped by fielding-circle restrictions, powerplays, and limits on repeated short-pitched bowling. The International Cricket Council playing conditions divide an innings into phases in which only a specified number of fielders may be outside the inner circle; the exact provisions have changed over time as the format has evolved.¹

Captains balance the value of aggressive stroke play against wicket preservation. The opening overs can reward attacking batsmen because of fielding restrictions, the middle overs often feature spin and controlled accumulation, and the final overs favor specialist “death” batting and bowling. Rain can shorten an innings or alter the target through a mathematical method; the Duckworth–Lewis–Stern system is the established framework used in many officially regulated matches.³

White clothing and red balls are generally associated with Tests, whereas ODIs use colored clothing and a white ball. Floodlights, fielding substitutes permitted under particular conditions, and video review have also become standard features of elite ODI cricket.

The first widely recognized ODI took place at Melbourne in January 1971, when Australia played England after a Test match was abandoned by rain; it was arranged as a one-day replacement rather than as the culmination of a long-established format.⁴ The experiment proved attractive to spectators and broadcasters, and limited-overs internationals gradually became a central form of international competition.

The first Cricket World Cup was held in England in 1975, using a 60-overs-per-side format; later editions standardized the competition around 50 overs.⁵ The ODI format subsequently expanded beyond its original leading nations as the ICC granted international status and developed qualification and ranking structures.

Men’s and women’s ODIs are both recognized international formats. Women’s ODIs have their own playing conditions and a major global tournament, the Women’s Cricket World Cup, reflecting the separate but parallel development of the women’s international game.

ODI records are strongly affected by changing playing conditions, so comparisons across eras require caution. Earlier matches used 60 overs, fielding restrictions differed, and some periods permitted two new balls, while modern regulations have altered how the ball ages and how teams plan their innings.¹

The format also contains several specialized edge cases. A match may be declared a no-result when insufficient play remains for a regulated result; a tie is distinct from a no-result; and tournament rules may use a Super Over or another procedure to separate tied knockout matches. Rain-revised chases can create targets that differ from a simple proportional reduction because the method models both overs and wickets remaining.³

ODIs have served as a testing ground for innovations later adopted elsewhere, including colored uniforms, day-night scheduling, video-assisted umpiring, and sophisticated workload management. They also occupy a distinct statistical category: an ODI century, five-wicket haul, or career record is not interchangeable with the corresponding Test or T20I achievement.
