Bowling spells (5)
I believe the answer is:
overs
'bowling spells' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for overs that I've seen before include "they may be limited internationally" , "Series of balls in cricket" , "Divisions of play in cricket" , "Bowling spells" , "Rounds of six bowls in cricket" .)
