Ball that one might wish a player would receive? (3,5)
I believe the answer is:
leg break
'ball that one might wish a player would receive?' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for leg break that I've seen before include "Spinning ball (cricket)" , "(In cricket) ball turning to the left on pitching" , "injury" , "Cricket delivery" , "Switch from on to off" .)
