FST fantasy analysts go through our 2018 fantasy baseball first base tiers and rankings. Our rankings are based on standard 5×5 scoring. Hitting categories include BA, HRs, Runs, RBIs, and SBs. While the rankings are based in large part on a player’s projected performance, we also take into account upside and risk. While several players are eligible at multiple positions, each player is only ranked once in their primary position.
