Steve Renko won 134 games while pitching for seven different clubs from 1969-1983. He had his best years for the Montreal Expos from 1970-1974.

Didier broke into the majors in 1969 with the Braves and had his best year. He played in 114 games for Atlanta, hitting .256 while driving in 32 runs. Didier never again came close to matching the games played or the production of his rookie campaign.

The RBIs and runs scored were also career highs. Menke was a the starting third baseman for the 1972 Cincinnati Reds who reached the World Series, where they lost to the Oakland A’s.
