Updated fantasy baseball draft rankings for OBP leagues (on-base percentage) in 2026. RotoBaller has the industry's #1 accuracy fantasy baseball rankings.
Opening Day is approaching rapidly, and some of the biggest fantasy baseball draft weekends are coming up. At RotoBaller, we have been providing fantasy baseball rankings for all different types of formats to help you win and crush your upcoming drafts. Points, roto, OBP, best ball, we've got you covered for all different formats. With that said, we have freshly updated our 2026 OBP Fantasy Baseball Rankings 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.
