ODI in cricket means One Day International: a match between international teams in which each side normally bats once for up to 50 overs. An ODI match is scheduled for one day. It combines a limited supply of deliveries with enough time for an innings to change direction.
For the wider context, start with our guide to the main cricket formats.
What does ODI mean in cricket?
The full form of ODI is One Day International. “One day” describes the match schedule; “international” refers to its official status. A domestic 50-over match is not automatically an ODI, and a rain-shortened ODI does not become a T20I.
How does a 50-over match work?
In an uninterrupted match, the first team sets a score and the second tries to beat it. An innings can end before 50 overs if the batting side is all out. The chase ends once the target is reached.
Here is an invented example: Team A scores 280. Team B needs 281 to win. At 140 after 25 overs, Team B needs another 141 from 25 overs. That is a required scoring rate of 5.64 runs per over, but the number of wickets left also matters.
With eight wickets available, the batting side has more room to take risks. With only three available, the same target may look much harder. Runs, balls and wickets need to be read together.
Why does an ODI innings have different phases?
Commentators often describe an opening phase, middle overs and a final push. These are useful ways to understand changing priorities, rather than a requirement that every team follow the same script.
An opener might first assess movement off the pitch. A middle-order pair might rebuild by finding singles and twos. Later, a set batter may attack more frequently because unused wickets have little value once the deliveries run out.
Imagine a side losing three wickets early. It can spend time repairing the innings, but it cannot rebuild indefinitely. A partnership is useful only if it also leaves a realistic route to a competitive total.
What do bowlers and captains have to manage?
A bowler can deliver a maximum of ten overs in a full 50-over ODI. Captains therefore have to spread their options across the innings, deciding whether to attack now or save a reliable bowler for later.
Suppose an opposition batter is struggling against one bowler. Extending that spell could produce a wicket, but it uses overs that might be valuable at the end. This is one reason an ODI can change through a decision that initially looks routine.
What happens if rain interrupts?
Rain can shorten a match and lead to a revised target under the Duckworth–Lewis–Stern (DLS) method. If insufficient play is possible, there may be no result. In an interrupted chase, use the official revised target rather than simply comparing the teams’ raw totals.
How is ODI cricket different from T20?
An ODI offers more deliveries to rebuild and plan a chase; T20 cricket compresses those decisions into a shorter innings. Neither format removes the need to balance scoring and survival. The balance changes with the situation.

ODI cricket FAQs
1. How many overs are there in an ODI?
A full ODI allows up to 50 overs per team, or 300 valid deliveries per innings. An innings can finish earlier if a team is all out or reaches its target; rain can also reduce the allocation.
2. What is the difference between ODI and T20?
ODIs normally allow 50 overs per side, while T20 matches allow 20. The ODI and T20 powerplay rules also differ, changing how captains protect the boundaries.
3. Can a batter be out LBW in an ODI?
Yes. LBW applies in ODI cricket as it does in other formats. Our LBW rules and examples explain why pad contact alone does not mean the batter is out.
Rules reference: ICC playing conditions. Examples in this guide are illustrative; competition-specific conditions and reduced-over matches can differ.
