Single forehand shot and scores are settled (2,4,8)
I believe the answer is:
no hard feelings
'scores are settled' is the definition.
(phrase used to show no one's holding a grudge)
'single forehand shot' is the wordplay.
'shot' indicates an anagram.
'single'+'forehand'='singleforehand'
'singleforehand' is an anagram of 'NO HARD FEELINGS'.
'and' is the link.
(Other definitions for no hard feelings that I've seen before include "Offering to appease" , "expected from the soft-hearted?" , "words of reconciliation" , "Forgiveness" .)
