In 1970 Thurman Munson was the near-unanimous Rookie of the Year. He received 23 of 24 votes, with the only other vote going to Roy Foster. Foster hit an impressive 23 homers while batting .268. His numbers and playing time dropped drasticly after the 1970 season and he was back in the minors by 1973. Munson went on to have what might have been a Hall of Fame career if it hadn't been tragically cut short.
The National League Rookie of the Year voting was much more diverse. Carl Morton got 11 of the 24 votes on the strength of an 18 win season for the last place Expos. Origianlly signed as an outfielder by the Braves, Morton helped his own cause by hitting a couple homers. Others getting R.O.Y. votes were Bernie Carbo, Larry Bowa, Wayne Simpson and Cesar Cedeno. Although no Hall of Famers, the list reads like a who's who of '70s semi-stars.
