Quite right...and he had the advantage of the Pesky pole in short right field...about 310' down the line...although I don't think he hit that many shots in that area.
I think the bull pen received more of his 4-baggers than any other area.
I don't have the figures right with me but I'll wager he picked up a whole lot of doubles off the Green Monster.
I don't know - if so, it wasn't by intent. Williams was a dead pull hitter, which is why Lou Boudreau invented the Williams Shift by moving the shortstop to the other side of 2nd base to defend him. In an old SI article, he said that he refused to go to the opposite field because he couldn't stand the thought of being late, i.e., having his hands ahead of the ball at contact, plus there was too small a margin of error. All of which makes his accomplishments, especially his lifetime batting average, even more impressive.
