You couldn't throw a fastball by Yaz. It just couldn't be done. And after 1967, pitchers threw at him all the time, often up at his head. He rarely got hit as he was so quick to spin out of the way and he would get right back in a swing even more ferociously. He would spin himself into the ground from swinging so hard. Yet he didn't strike out a lot.
You mentioned the 1975 All Star Game. I remember it. He was sent up to PH against Tom Seaver. They didn't have a helmet for Yaz so he went up to bat with his Red Sox hat and inside protector and he blasted the first Seaver pitch for a 3 run Home Run to either tie the game of put them ahead. Instead of keeping Yaz in the game, the manager, Alvin Dark from Oakland put his play Claudell Washington in the game in LF. I think he made an error in the field or a misplay or pilled a rock on the bases, but I remember him screwing up. The AL lost and the papers the next day criticized Dark for not keeping Yaz in the game.
In the 1975 ALCS, Yaz was forced back to LF by Jim Rice's injury and he dominated the series defensively in LF. I can't remember a LFer ever dominating a series defensively like that.
