Step 1 : Introduction to the question "How many overs a bowler can ball in one inning in an ODI?"
...Each bowler is restricted to bowling a maximum of 10 overs (fewer in the case of rain-reduced matches and in any event generally no more than one fifth or 20% of the total overs per innings). Therefore, each team must comprise at least five competent bowlers (either dedicated bowlers or all-rounders).
