Throw-out before a score? Attempt might pay off (5,1,3)

Ross

I believe the answer is:

worth a try

'attempt might pay off' is the definition.

'throw-out before a score?' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'before' says to put letters next to each other.
'score?' becomes 'try' ().
'throw' anagrammed gives 'worth'.
'worth'+'a'+'try'='WORTH A TRY'

I've seen this clue in The Guardian.
