Try a story, no. 1 usually? (6)
I believe the answer is:
goalie
'no 1 usually?' is the definition.
I can't judge whether this defines the answer.
'try a story' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'story' becomes 'lie' (story can mean a fabrication).
'go'+'a'+'lie'='GOALIE'
Can you help me to learn more?
(Other definitions for goalie that I've seen before include "number one" , "Football team member" , "Soccer player who protects the target" , "Football player" , "Keeper (colloq.)" .)
