A few points before we get into the meat, of picking the best player at each position, including two pitchers: starter and relief. This is based on numbers put up across all levels over the course of the 2021 campaign. Factors taken into account include: level, age relative to level, park factor, playing time and pre-season expectations (more or less as a tiebreaker). A player is only eligible at one spot: this is the position on the diamond at which he appeared most often. In terms of spots here (though not PA to determine eligibility), I am combining outfield positions, with three players chosen there.
