MLB Same-Game Parlay Hitter Trend Dataset for Total Bases and RBI Research

Question this dataset helps answer

Which MLB hitters historically clear same-game parlay legs like 1+ hit, 2+ total bases, 1+ RBI, 1+ run, or 1+ home run, and what pregame form plus opposing-starter context was present before first pitch?

Short answer

This dataset helps sports-betting researchers, fantasy baseball analysts, and dashboard builders investigate which MLB hitters clear common same-game parlay legs using rolling hitter form, matchup history, team context, and opposing-starter trends.

What the public preview proves

• Which teams, hitters, parks, and seasons are represented in the sample
• Which columns are usable as pre-event hitter or opposing-starter features versus post-event outcomes
• Which rows already support total-bases, hit, RBI, run-scored, and home-run screening workflows

Public preview vs full dataset

• Preview: 8391 rows and 122 columns
• Full: 167824 rows and 122 columns

The full dataset includes 167824 rows across MLB hitter-game observations, making it large enough for dashboard analysis, historical filtering, same-game parlay research, and exploratory modeling workflows.

Responsible use note

This dataset is for research, analysis, dashboard building, educational use, and exploratory modeling. It does not provide betting advice, picks, guarantees, or predictions of future outcomes.

Modeling notes

• Each row represents one hitter in one completed MLB regular-season game.
• Pre-event features include rolling hitter form, matchup history versus the opponent team, team context, and opposing-starter trend features.
• Outcomes include actual hits, total bases, RBI, runs, home runs, and threshold-hit flags for the completed game.
• The sample is meant to prove schema, coverage, and row meaning rather than replace the full dataset.

Use Cases

• Compare which hitters historically clear hit, total-bases, RBI, run-scored, or home-run thresholds.
• Screen hitter rows by recent form, batting-order slot, opponent-team history, or opposing-starter context.
• Build time-aware notebooks that keep pregame hitter features separate from postgame outcomes.
• Filter by team, opponent, venue, or starter trends before building dashboards or exploratory models.
