Bar close to outfield reserved (5)
I believe the answer is:
saved
'reserved' is the definition.
(saving is a kind of reserving)
'bar close to outfield' is the wordplay.
'bar' becomes 'save' (save is a kind of bar**).
'close to' says to take the final letters (the close/ending of).
The last letter of 'outfield' is 'd'.
'save'+'d'='SAVED'
(Other definitions for saved that I've seen before include "Conserved" , "Preserved" , "Stored for future use" , "Redeemed or rescued" , "Prevented from dying" .)
