Sees runs hit with certainty (8)
I believe the answer is:
sureness
'certainty' is the definition.
(sureness is a kind of certainty)
'sees runs hit' is the wordplay.
'hit' indicates an anagram.
'sees'+'runs'='seesruns'
'seesruns' with letters rearranged gives 'SURENESS'.
'with' is the link.
(Another definition for sureness that I've seen is " confidence".)
