The 1878 Boston Red Stockings
Tommy Bond started 59 games of the 60 game season for the Boston Red stockings in 1878. His record was 40-19. He pitched 532.2 innings with an ERA of 2.06 If he played today he would probably earn $45 million a year. Baseball-Reference only lists a 10 man roster for Boston's 1878 team.
Bond was the only dedicated pitcher. Jack Manning was the only other player to pitch for Boston that season. He was primarily an outfielder who only pitched in 3 games. I'm guessing they didn't have a disabled list back then. Nobody got hurt back then, or when they did they played anyways.
Pre 1900's baseball has sparked my interest. Have to look into it more as its fun to see how the game evolved. Without the Boston Red Stockings there probably would never have been the Boston Red Sox. Actually The Red Stockings are considered to precede the Boston Bean Eaters and are part of the heritage of the Braves. Still the Red Stocking franchise moving out of Boston made room for the Red Sox eventually.
Boston Bean Eaters, now there was a good name for a baseball team.
