Stats updated: Jul 29, 2026 — nightly box scores, not live.
Edwin Arroyo has gone over 0.5 RBI in 1 of his last 10 decided games (10%), measured against our typical-game line.
Pick any line — standard, demon (harder, pays more), goblin (easier, pays less), or an alternate with its payout multiplier — and the whole read updates to it. Only the standard line takes an under; every other variant pays the over only. Each rung’s FireFactor is scored against its OWN payout breakeven — 0 means fairly priced for that payout, not a coin flip — so rungs compare directly. The bar uses the best information available: an exact posted multiplier, else the market’s de-vigged sportsbook odds at that exact line, else a published-payout approximation.
Typical entry payouts (verify in the app — they change and can vary by state): Power Play 2-pick 3×, 3-pick 5×, 4-pick 10×. Flex Play 3-pick 2.25× (1.25× one miss), 4-pick 5× (1.5× one miss), 5-pick 10× (2× / 0.4× on misses), 6-pick 25× (2× / 0.4× on misses).
Demons: Adding a demon raises the whole entry’s payout multiple (a harder line buys a bigger multiplier). Demons can only be taken as More.
Goblins: Adding a goblin lowers the whole entry’s payout multiple (an easier line costs payout). Goblins can only be taken as More and aren’t combinable with everything — the app shows the exact adjusted payout.
Scored against this payout variant's ~35% breakeven — 0 means fairly priced for its payout, not a coin flip. Descriptive research from past games — not betting advice.Small samples and hot streaks are discounted by a 95% Wilson lower bound (the trust factor), so a thin streak can’t masquerade as an edge.
Over 0.5 RBI by situation, each with its own confidence — thin splits read Low, so a small-sample “crushes at home” doesn’t masquerade as an edge.

FavorableOver his last 10 games, Edwin Arroyo has gone over 0.5 RBI 1 of 10 decided times (10%) — versus 14% across the full season. WSH has been a favorable matchup for hitters this season, allowing the 3rd-most RBI of 30 teams (5.0 per game). His game-to-game RBI have been highly variable (σ ≈ 0.3), so short streaks can mislead.

Hit rate excludes pushes from the denominator. Confidence uses a 95% Wilson interval — a high recent rate on few games still reads as low confidence. Season over rate at this line: 14%.
