Updating the Tiers
Welcome to the Baseball Prospectus in-season rankings update to our preseason positional tiers article. As we did before Opening Day, players at each position will be divided into five tiers, represented by a “star” rating. In addition, unlike with the preseason “star” ratings, these lists can also be viewed as a straight ranking. Here's how to define the stars:
Five-star players are the studs at their position. In general, they are the players who will provide first or second round draft value and will be worth $30 or more in auction formats. Four-star players are a cut below the studs at the position. They will earn more than $20 in auction formats. Three-star players are the last tier in which players are projected to provide double-digit dollar value in auctions, and two-star players are projected to earn single digits in dollar value in auctions. One-star players are the types of players who provide back end roster value. The positional tiers aren't simply a regurgitation of what has happened year-to-date but rather try to offer some insights into what we expect will happen the rest of 2017.
If you are wondering why a specific player isn’t listed, please note that in many cases players in the one-star tier and players who are not ranked are interchangeable.
The rankings assume a 15-team, standard 5x5 Roto scoring format, with 23-man rosters and the following positions: C (2) 1B (1) 2B (1) 3B (1) SS (1) CI (1) MI (1) OF (5) UT (1) P (9). Position eligibility is based on either 20 games at the position last year or five games this year.
Here’s the schedule:
