For six seasons, from 1972 to 1977, Bill Plummer was the backup to Johnny Bench at catcher for the Cincinnati Reds. That meant few people realized who he was or cared. They only knew he wasn't Bench.
He was on three pennant-winners with the Reds but he never saw any action in the postseason. He did get two rings when The Big Red Machine won titles in 1975 and 1976.
His best year was in 1976 when Bench had an unusual off-season. That year he got 40 starts and appeared in 56 games, and Plummer hit six doubles, four homers, and 19 runs batted in. Probably the biggest game of his career came on June 6, 1976, when he had three hits against the Cardinals, including a triple and a three-run homer. That day he had seven RBIs in the Reds 13-2 win.
