So, a major league baseball team has nine players on the field. Which player is the most important? Defend your decision. So, quite honestly, to answer this question, I don't really know anything about baseball, so I wouldn't be able to answer this question if I did have more knowledge on baseball, though I can. I'm not sure if I can do research and answer this question, but yeah, quite honestly, I don't have the baseball experience or know anything about it at all. So, that's my answer for this question.
