See about jerk leading the baseball team (7)
I believe the answer is:
yankees
'baseball team' is the definition.
(New York Yankees)
'see about jerk leading' is the wordplay.
'about' says the letters should be written backwards.
'jerk' becomes 'yank' (synonyms).
'leading' says to put letters next to each other.
'see' written backwards gives 'ees'.
'ees' put after 'yank' is 'YANKEES'.
'the' acts as a link.
(Other definitions for yankees that I've seen before include "Code words on the radio for US" , "Northern soldiers in the American Civil War" , "Side in US Civil War" , "Americans (sl.)" , "NY baseball team" .)
