Pitcher, in slang (6)
I believe the answer is:
hurler
(Other definitions for hurler that I've seen before include "Henry Shefflin or Christy Ring, say" , "member of Irish sports team" , "Henry Shefflin or Tony Kelly, say" , "Player of Irish game resembling hockey" , "Henry Shefflin or Se?n ?g ? hAilp?n, say" .)
