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 compare, screen, and investigate MLB hitter-leg context using pregame rolling form, opponent-team history, and opposing-starter trend signals.

What the public preview proves

• Which hitters, teams, parks, seasons, and opposing starters are present in the sample
• Which fields are usable as pre-event hitter-context features versus post-event outcomes
• Which rows already support hit, total-bases, RBI, run-scored, and home-run threshold analysis

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.

This product is built around a specific buyer problem rather than a generic baseball export. Plenty of public MLB game logs exist, but buyers who care about same-game parlay research still have to do the expensive part themselves. They need to engineer rolling hitter form, keep opponent-team history time ordered, separate pregame information from postgame results, identify the actual opposing starter, summarize that starter's recent form, and then align all of it with the exact hitter outcomes they care about. Generic game logs do not answer that workflow cleanly. This dataset does.

Each row represents one hitter in one completed MLB regular-season game from the 2023 season through June 11, 2026. The full file contains 167824 rows across 122 columns. That row volume matters. It is large enough for league-wide filtering, season-over-season comparison, team-level screening, hitter dashboards, threshold studies, and time-aware exploratory modeling. Buyers can analyze hitters by team, by venue, by batting-order slot, by recent form, by opponent-team history, or by opposing-starter context without shrinking the work to a toy sample.

The pre-event side of the table is the core commercial value. Every row includes rolling hitter form such as recent plate appearances, hits, total bases, runs, RBI, and home runs. It also includes team context that existed before first pitch: home-away status, recent team offense, recent opponent defense, days since the hitter's last game, days since the team's last game, and the identity of the opposing probable starter. On top of that, the dataset adds opposing-starter features that are difficult to maintain by hand: prior starts, days since prior start, rolling innings, hits allowed, earned runs, walks, strikeouts, home runs allowed, rolling ERA, rolling WHIP, and season-to-date ERA based only on earlier starts.

The matchup-history layer is what makes the product different from a normal hitter game log. A buyer can filter directly for hitters that already have opponent-specific history, compare recent 2+ total-bases rates across similar batting-order roles, or screen for hitters facing starters who have recently allowed more hits, walks, or earned runs. They can also compare whether the hitter's team has entered the game in a stronger offensive stretch while the opponent has been allowing more recent production. The dataset is positioned as research infrastructure for those questions, not as a recommendation engine.

The post-event side of the table captures what actually happened in the completed game. That includes hits, total bases, RBI, runs, home runs, walks, strikeouts, and threshold-hit flags such as 1+ hit, 2+ hits, 2+ total bases, 3+ total bases, 1+ RBI, 1+ run, and 1+ home run. This is deliberate. The table keeps a clear separation between pre-event features and post-event outcomes so buyers can use it for responsible historical analysis, train-test workflows, and dashboard building without guessing which fields leak future information.

Because the build uses official MLB schedule and boxscore endpoints, the source path is transparent and reproducible. Buyers are not depending on a mystery feed. The dataset keeps official identifiers for the game, hitter, teams, and opposing starter, which means analysts can join it to their own park, weather, DFS, or projection workflows if they want to extend the research. The core product value is that they do not have to hand-build the time-ordered hitter or starter context first.

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. It should not be marketed as a way to guarantee winning parlays, beat sportsbooks, or produce certain returns.

Modeling notes

• Each row represents one hitter in one completed MLB regular-season game.
• Pre-event features include rolling hitter form, opponent-team history, team offense or defense context, and opposing-starter trend fields.
• Post-event outcomes include the hitter's actual box-score line plus threshold-hit flags for common same-game parlay leg types.
• The coverage window runs from the 2023 season through June 11, 2026.
• The full dataset contains 167824 rows, which is large enough for train-test splits by date, by season, by team, by batting-order slot, or by minimum opponent-history depth.
• A sensible modeling workflow should split by date or season rather than shuffle randomly because the hitter and starter features are time ordered.
• Opposing-starter features are based on actual completed prior starts, so they are best interpreted as historical research context rather than guaranteed future starter availability.
• The threshold-hit flags are historical outcomes for analysis, not suggestions for future wagers.
• The dataset is descriptive infrastructure for hitter research, not a finished betting model.

Why the free sample matters

The public sample proves the commercial claim quickly. A buyer can inspect the schema and immediately verify that the file is not just a copied hitter game log. They can see stable hitter-game identifiers, official starter identifiers, recent hitter-form fields, recent starter-form fields, opponent-history rates, team-context features, and actual hitter outcomes. They can also check whether the seasons, teams, parks, and stat types they care about are present before paying for the full file. That is what the public sample is supposed to do: prove the buyer task, the row meaning, and the quality of the enrichment.

Source and build notes

The build uses the official MLB Stats API schedule feed plus official game box scores, then computes rolling hitter, team, opponent, and starter features locally with time-ordering preserved. This avoids a common DIY mistake where analysts accidentally mix future results into historical hitter research. The output is a single, analysis-ready table rather than a stack of raw JSON files that still need player-game parsing, rolling-feature engineering, and starter-context joins.
