Take a look at Saunders career. He has never hit in clutch situations, hence he has never had many season rbi,s.
Smoak, same thing. poor clutch, poor rbi,s every year.
Great hitters control the situation. fowling off pitches until they get one they like, taking advantage of pitchers mistakes,
hitting to defensive weaknesses, sure there is some luck involved, but are good hitters lucky, and poor hitters unlucky?
Don't think so.
