Comes across English baseball team outside (5)
I believe the answer is:
meets
'comes across' is the definition.
('meet' can be a synonym of 'come across')
'english baseball team outside' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'baseball team' becomes 'mets' (New York Mets).
'outside' indicates putting letters inside (some letters go outside others).
'e' placed into 'mets' is 'MEETS'.
(Other definitions for meets that I've seen before include "Comes across" , "Effectively copes with" , "Hunts" , "Joins with" , "Encounters or suffices" .)
