'awkward delivery' is the definition.
'breech' can be an answer for 'delivery' (breech delivery is a kind of delivery). I am not sure about the 'awkward' bit.

'bowled on repeat endlessly' is the wordplay.
'bowled on' becomes 'b' (cricket abbreviation. I am not sure about the 'on' bit.).
'repeat' becomes 're-echo' (re-echoing is a kind of repeating).
'endlessly' means to remove the last letter.
'reecho' with its final letter taken away is 'reech'.
'b'+'reech'='BREECH'
