Earl Weaver, who liked to platoon, had the ultimate when he had Eddie Murray and Ken Singleton batting 3rd and 4th. Both were switch hitters, so he could just leave them in the lineup and work at the other seven slots in the lineup. I was always envious of the Orioles having those two in the lineup together.
Singleton’s biggest and basically only weakness was he was slow. Baseball slow, not real life slow. He would re-lap me in a race. He had a good arm in right field but was at best as a barely above average fielder in his two prime years, ages 25 and 26. Otherwise he was a below average fielder, switching more and more to DH at the end of his career. However, at the age of 32 in 1979 he is according to Baseball Reference plus 3 runs, which has to be one of the greatest fluke seasons of all time. He was 3 for 4 as a base stealer, so that would only be a very small part of it. For his career Singleton was 21 for 57 as a base stealer. It was usually best if he didn’t run.
Another thing interesting looking at his stats closely was in 1979 at the age of 32 he hit 11 more homeruns (35) than any other season.
