Went too far over for a try (8)
I believe the answer is:
overshot
'went too far' is the definition.
(I've seen this before)
'over for a try' is the wordplay.
'for' means one lot of letters go next to another.
'a try' becomes 'shot' (shot is a kind of try**).
'over'+'shot'='OVERSHOT'
(Other definitions for overshot that I've seen before include "needed to pull back?" , "Went too far" , "was pitched wrong?" , "Went past the target" , "Went beyond the mark" .)
