Stokes is bowling? That's a blessing! (7)
I believe the answer is:
benison
'that's a blessing' is the definition.
(benison is a kind of blessing)
'stokes is bowling?' is the wordplay.
'stokes' becomes 'ben' (cricketer Ben Stokes).
'bowling?' becomes 'on' (I can't justify this - if you can you should give a lot more credence to this answer).
'ben'+'is'+'on'='BENISON'
(Other definitions for benison that I've seen before include "Benediction" , "Thanksgiving" , "Sob, nine turn into a blessing" .)
