1903 Boston Americans

Each position shows the card of the player who played it most and is in the collection — or, with no card yet, the name of the player who played it most. “+N” lists everyone else who played there. Any pitcher's card can take the mound, a starter's first; the rotation panel shows the next four starters and the bullpen the relievers (closer first), cards in the collection first. Click a card or a name to see all of that player's cards for 1903. “Field positions filled” counts player cards placed at a field position; manager, team, special and Copy cards do not count.
