Welcomed in dugout, a venerable English scorer (7)
I believe the answer is:
tavener
'english scorer' is the definition.
(Sir John Kenneth Tavener 1944-2013, composer)
'welcomed in dugout a venerable' is the wordplay.
'welcomed in' indicates a hidden word.
'TAVENER' is hidden within 'dugout a venerable'.
(Other definitions for tavener that I've seen before include "One in a bar" , "Modern composer, John (not the 16th century one)" , "British composer, b. 1944 (not the 16th century one)" .)
