RotoBaller's OBP fantasy baseball rankings and draft tiers for 2026 on-base percentage leagues including hitters and pitchers (C, 1B, 2B, 3B, SS, OF, SP, RP).
The thick of the 2026 fantasy baseball offseason is finally here. At RotoBaller, we continue generate fantasy baseball rankings for all types of formats to help prepare you for your upcoming drafts. Today, we focus on on-base percentage formats with our 2026 OBP Fantasy Baseball Rankings for on-base percentage (OBP) leagues. These OBP rankings include hitters and pitchers for the top 750 players (across all positions).
These fantasy baseball rankings are designed for OBP leagues and scoring rules, for leagues that use OBP as a scoring category, and are put together by our MLB team lead, Nick Mariano. Many times, OBP leagues will not have AVG as a category -- as OBP is the replacement category for AVG -- but it doesn't have to be that way necessarily.
For those who are not very familiar, OBP means on-base percentage. To put it simply, OBP measures a hitter's ability to get on base in a variety of ways, including hits, walks, and hit-by-pitches. Batting average (AVG) only accounts for hits. Some fantasy baseball leagues prefer OBP, as hitters who walk a lot will be rewarded more and have increased value. Therefore, in the rankings below, you'll see players with high OBPs and walk-rates ranked higher than they would be in our classic fantasy baseball rankings for roto leagues.
