Grip had to change, racket drawn back (8)
I believe the answer is:
adhesion
'grip' is the definition.
(grip is something's adhesion to a surface)
'had to change racket drawn back' is the wordplay.
I cannot quite see how this works, but
an anagram of 'had' is 'adh' which is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for adhesion that I've seen before include "Adonis, he may be a sticker" , "Tackiness" , "Stickiness" , "The property of sticking" , "He's no aid to sticker" .)
