Part of foot stumped English player, initially batting first (6)
I believe the answer is:
instep
'part of foot' is the definition.
(I've seen this before)
'stumped english player initially batting first' is the wordplay.
'stumped' becomes 'st' (I've seen this in other clues).
'initially' indicates taking the first letters.
'batting' becomes 'in'.
'first' means one lot of letters go next to another.
The initial letters of 'english player' is 'ep'.
'st'+'ep'='step'
'step' put after 'in' is 'INSTEP'.
(Other definitions for instep that I've seen before include "One part of Oxford" , "Part of foot under spinet" , "Section of foot" , "Top of foot" , "Arch we stand on" .)
