Hurling player? No, baseball (7)
I believe the answer is:
pitcher
'hurling player?' is the definition.
'pitcher' can be an answer for 'player?' (I have seen 'American player' mean 'pitcher' so perhaps 'player' could also mean 'pitcher'). I am not sure about the 'hurling' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pitcher that I've seen before include "Ewer" , "Baseball bowler and container for liquid" , "Baseball thrower or water jug" , "One throwing" , "Someone promoting" .)
