Why Luis Garcia Jr. Under 0.5 Runs Scored vs Christian Scott?
PropsBot’s AI models assigned a 68.5% Confidence Score to Luis Garcia Jr. clearing under 0.5 runs scored in this spot. That number lands in the High Confidence band. Edge Score is 0.0% — the model’s read of how mispriced the Fliff line is right now. Confidence Gap sits at +9.3%, the spread between PropsBot’s modeled probability and the 59% baked into the market.
Historical Performance at 0.5 Runs Scored
Luis Garcia Jr. has cleared under 0.5 runs scored in 4 of his last 5, 7 of his last 10, and 12 of his last 20. The H2H vs Christian Scott sits at 75%, and his season mark against this line is 59%. The L5 → L10 → L20 walk-down tells you the recent run is doing the heavy lifting; the season is the regression target.
Matchup Context: NYM @ WAS
Christian Scott is a right-handed starter giving up roughly the league-average run environment. Washington’s implied team total tonight is 4.4 runs and the spread sits at 1.5 — Mets favored. Game O/U 10.0 isn’t tiny, but the run distribution skews to the Mets side, and Garcia hitting near the bottom of a 4.4-run lineup against a starter who’ll likely go 5+ innings is the dictionary definition of a low-scoring-spot Under.
Best Line Available
Fliff’s -145 is the cheapest juice across the market on this Under. Implied probability there is 59%; the model wants 68%. That gap (the +9.3% Conf Gap shown on the card) is the whole reason this pick clears the High Confidence band even with Edge sitting at 0.0% — the books are clustered around the same number, so the edge per book is thin, but the average market line is mispriced relative to where Garcia’s bat plays in this lineup spot.
How PropsBot Grades MLB Runs Scored Picks
Every PropsBot pick is graded the morning after the game by an automated result-tracker that pulls box-score data from MLB.com / NHL.com / NBA.com / NFL.com and marks the pick Hit, Miss, Push, or Voided (for player non-appearance). The graded outcome is appended to the post via a green/red callout block, and the per-pick history is published at Performance Methodology. Every entry includes the date, line, book, and graded outcome — nothing is retroactively edited.
How PropsBot Models MLB Runs Scored Props
Garcia’s running a .301 OBP and just 0.43 runs per game in 2026 — Washington’s lineup chart shows him batting at the bottom third and the team OPS sits at .612. Sprint speed is .7 ft/s, which is real wheels, but you only score from the basepaths when guys behind you knock you in. The Nats don’t. Multiple AI models score the prop, then their consensus is summarized into a single Confidence Score and an Edge Score — full methodology at /performance-methodology/.
