1967 was the season of the Yaz. Like Frank Robinson one year earlier, Yastrzemski won the triple crown and led his team to the World Series. Unlike Robby, Yaz' team didn't win, nor did he finish ahead of all others in home runs. Lost in the hype is the fact that Harmon Killebrew was tied for the lead in homers.
Four AL players finished with a .300 or better average. That doesn't sound like a lot, but the following season, only Yastrzemski would accomplish that, with a .301 average. Following that, the mound was lowered, 40 minor-league pitchers were given major-league jobs (expansion), and
As usual, the same 5 or 6 players seem to fill the 9 spots on these leader cards.
Yaz was one-and-done in the late-1960s' home run derby, while Killebrew and Frank Howard would make multiple appearances on these cards.
