Cricketer mostly opening is for the high jump, for example (5,5)
I believe the answer is:
field event
'high jump for example' is the definition.
(high jump is a kind of field event)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for field event that I've seen before include "Perhaps shot put" , "hammer, say" , "the javelin, say" , "contest" .)
