Smoothly played to leg, maybe, with the middle of the bat (6)
I believe the answer is:
legato
'smoothly' is the definition.
(I've seen this before)
'to leg maybe with the middle of the bat' is the wordplay.
'maybe with' indicates anagramming the letters.
'the middle of' means to look at the middle letters.
The central letter of 'bat' is 'a'.
'to'+'leg'='toleg'
'toleg' with its letters anagrammed with 'a' can make 'LEGATO'.
'played' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for legato that I've seen before include "scored smoothly" , "Smoothly, musically speaking" , "Got ale (anag.)" , "Smoothly (mus.)" , "Smoothly flowing (music)" .)
