Wow, that's a lot better list than the NL winners.
Pinella had to wait until 1973 to get a card. He also got into the 1975 and 1977 sets.
Munson had to wait until 1976. He then appeared in 1977 and 1978. I would have loved to see him in the 1971 set.
Chambliss had to wait until 1977. He appeared in three more sets.
Carlton Fisk first appeared in 1973 after his ROY award. He showed up four more times.
Al Bumbry had a nice career but no Kellogg's cards.
Mike Hargrove appeared four times but not until 1976.
Fred Lynn appeared in 1976 after his ROY/MVP season. He showed up four more times.
Mark Fidrych also showed up after his ROY season. That was his only appearance in a Kellogg's set.
Alfredo Griffin - see Lou Whitaker. No Kellogg's card.
John Castino got into the 1982 Kellogg's set.
Joe Charboneau got into the 1981 set after being ROY. That was it for him.
Four players got a Kellogg's card in the year after being ROY. Ten of the 15 winners got a Kellogg's card at some point.
