Declare at cricket match (6)

I believe the answer is:

attest

'declare' is the definition.
(attesting is a kind of declaring)

'at cricket match' is the wordplay.
'cricket match' becomes 'test' (a test is a kind of cricket match).
'at'+'test'='ATTEST'

(Other definitions for attest that I've seen before include "Declare (that something is the case)" , "Give evidence - sounds a trial" , "Vouch for" , "Give proof" , "Declare to be true or genuine" .)

I've seen this clue in The Guardian, The Daily Express and The Mirror.
