Merv Rettenmund had the good fortune to play for two of the best teams of his era: the 1969-1971 Baltimore Orioles and the Big Red Machine Cincinnati Reds. He could play any of the three outfield spots and he had good pop in his righthanded bat. He was a very good pinch-hitter: in over 300 plate appearances as a pinch-hitter, he batted .275 with five homers and an excellent .422 on-base percentage. His best season was in 1971 for Baltimore when Earl Weaver (who considered Rettenmund one of the most useful role players he ever had) used him as a fourth outfielder, getting him into 141 games. He hit .318 with 11 homers, 75RBIs, and an impressive .422 on-base percentage. Despite not having a set position, Rettenmund received eight votes for MVP that year. He won World Series titles with the O's in 1970 and the Reds in 1975, and from 1969 to 1975 his teams made the playoffs five times in seven years. Later, in his last full season in the big leagues Rettenmund was a spare outfielder and DH for the Angels when they won the '79 AL West division title.
