Advanced runs to block improved team's attacking options? (7,7)

'advanced' is the definition.
('bring forward' can be a synonym of 'advance')

'runs to block improved team's attacking options?' is the wordplay.
I cannot quite see how this works, but
'runs' could be 'r' (cricket abbreviation) and 'r' is found in the answer.
'to' could be 'for' and 'for' is present in the answer.
'block' could be 'ward' (ward is a kind of block) and 'ward' is found in the answer.
The remaining letters 'bought' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
