Second eleven shown in book mate circulated (7,4)

I believe the answer is:

reserve team

'second eleven' is the definition.
(reserve football or cricket team)

'book mate circulated' is the wordplay.
'book' becomes 'reserve' (as in booking or reserving in advance).
'circulated' indicates an anagram.
'mate' anagrammed gives 'team'.
'reserve'+'team'='RESERVE TEAM'

'shown in' is the link.

(Another definition for reserve team that I've seen is " Second eleven".)

I've seen this clue in The Times.
