Played smoothly to leg, maybe, out of the middle of the bat (6)
I believe the answer is:
legato
'played smoothly' is the definition.
(I've seen this before)
'to leg maybe out of the middle of the bat' is the wordplay.
'maybe' indicates an anagram.
'out of' means one lot of letters goes inside another.
'the middle of' means to look at the middle letters.
The middle letter of 'bat' is 'a'.
'to'+'leg'='toleg'
'toleg' is an anagram of 'legto'.
'legto' going around 'a' is 'LEGATO'.
(Other definitions for legato that I've seen before include "Smoothly-flowing" , "Don't play roughly" , "In a smooth and flowing manner (music)" , "Played smoothly" , "running into each other" .)
