As usual, the Indians are well-represented, with 5 of the 10 slots. Luis Tiant appears on all 3 cards!
But the White Sox (who regularly appeared here for the last few years) are nowhere to be found - replaced by 2 appearances each for Dave McNally and Denny McLain. (McLain was fresh off his 31-win performance and World Series championship.)
Besides McLain, the other (mere) 20-game winners were McNally, Tiant, and Mel Stottlemyre, with Mel keeping these cards from being just a 4-person Indians/Tigers/Orioles production.
