by The following 2018 fantasy baseball relief pitcher rankings are based on standard 5×5 scoring. Pitching categories include Wins, ERA, WHIP, Ks, and Saves. 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.
