First to get over splintered railing (8)
I believe the answer is:
Here is my best explanation:
'first' is the definition.
('original' is associated in meaning with 'first')
'get over splintered railing' is the wordplay.
'get' is a charade indicator (letters next to each other).
'over' becomes 'o' (cricket abbreviation**).
'splintered' indicates anagramming the letters.
'railing' is an anagram of 'riginal'.
'o' next to 'riginal' is 'ORIGINAL'.
'to' is the link.
