Shabby as a Wimbledon ace? (5)
I believe the answer is:
seedy
'shabby' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for seedy that I've seen before include "Scruffy" , "Raspberry jam might be" , "Sordid and disreputable" , "run down" , "Nasty and squalid" .)
