Spell
Spell – the number of successive overs in which the bowler participates until his replacement. As an explicit example, we can analyze the situation when bowler scores (1, 3, 5, 7, 9) in the first ten overs of an ODI match before another player comes in and scores 11th instead. Thus, it is considered to spell the first player for 5 overs. It is worth noting that all spells have sequential numbering starting from the first, second, third, etc.
