dkOBA (DraftKings On-Base Average) is an advanced baseball stat that measures how many DraftKings fantasy points a hitter generates per plate appearance. Unlike traditional OBP which treats all ways of reaching base equally, dkOBA weights each outcome by its actual DraftKings scoring value.
This makes dkOBA the most direct measure of a hitter's DFS scoring efficiency on DraftKings — a player with a high dkOBA consistently produces more fantasy points per opportunity than one with a low dkOBA, regardless of batting average or traditional stats.
dkOBA Formula
dkOBA = (2×BB + 3×1B + 5×2B + 8×3B + 10×HR) ÷ PA
Each outcome is weighted by its DraftKings point value:
A minimum of 30 plate appearances is required for a reliable dkOBA calculation. Players below this threshold are assigned a default value of 1.05.
What is a Good dkOBA?
League average dkOBA is typically around 1.05–1.10. Values are calculated per-matchup, so the same hitter will have different dkOBA vs LHP and vs RHP.
dkOBA vs Traditional OBP
Traditional OBP treats a walk the same as a home run — both count equally as "reaching base." For DFS, this is misleading because a HR is worth 5× a walk on DraftKings.
dkOBA solves this by weighting each outcome proportionally to its DK scoring value. A hitter who walks a lot but rarely hits for power will have a high OBP but a mediocre dkOBA.
This is why dkOBA is a better predictor of DraftKings scoring than OBP, OPS, or even wOBA for DFS purposes.
How FTA Uses dkOBA in MLB Projections
FTA calculates each hitter's dkOBA against today's specific opposing pitcher, adjusted for platoon matchup (vs LHP or vs RHP). This daily, matchup-specific calculation is what makes our projections different from static season-long stats.
dkOBA is weighted at 30% of the overall FTA Rating for hitters — the single largest input to our projection model. It's also weighted at 45% of ceiling ratings, making it the dominant factor in identifying tournament upside.
FTA Rating Weights (Hitters):
Using dkOBA for Cash Games
In cash games, prioritize hitters with consistently high dkOBA across both platoon splits. A hitter with 1.25+ dkOBA vs both LHP and RHP is a safer floor play than someone with 1.50 vs one hand and 0.85 vs the other.
Using dkOBA for Tournaments
In tournaments, target hitters with elite dkOBA in today's specific matchup, even if their overall season stats are average. A platoon advantage (e.g., lefty hitter vs RHP with 1.60 dkOBA) can create tournament-winning ceilings at low ownership.
Data Source & Methodology
dkOBA values are calculated using batting statistics from the MLB Stats API and Baseball Savant, split by pitcher handedness (vs LHP and vs RHP). Projections are updated daily for each game's specific matchup. DraftKings scoring weights are current as of the 2026 MLB season.
