'tactical talent at flushing meadows' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'margaret with skill' is the wordplay.
'margaret with' becomes 'court' (I can't justify this - if you can you should give a lot more credence to this answer).
'skill' becomes 'craft' (craft is a kind of skill).
'court'+'craft'='COURTCRAFT'

'shows' acts as a link.
