Turn at batting (7)
I believe the answer is:
innings
'turn at batting' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for innings that I've seen before include "Time at the crease - a good one's a long life" , "Batting stint" , "Period at the wicket" , "A team's turn at batting" , "Time at the wicket" .)
