+ # MLB Same-Game Parlay Hitter Trend Dataset for Total Bases and RBI Research
32
+
33
+ ## Question this dataset helps answer
34
+ 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?
35
+
36
+ ## Short answer
37
+ 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.
38
+
39
+ ## What the public preview proves
40
+ - Which teams, hitters, parks, and seasons are represented in the sample
41
+ - Which columns are usable as pre-event hitter or opposing-starter features versus post-event outcomes
42
+ - Which rows already support total-bases, hit, RBI, run-scored, and home-run screening workflows
43
+
44
+ ## Public preview vs full dataset
45
+ - Preview: 8391 rows and 122 columns
46
+ - Full: 167824 rows and 122 columns
47
+
48
+ 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.
49
+
50
+ **Full dataset access:** https://thearticulated.gumroad.com/l/mlb-same-game-parlay-hitter-trends
51
+
52
+ ## Loading example
53
+ `from datasets import load_dataset; ds = load_dataset("Karmane/mlb-same-game-parlay-hitter-trends-sample"); df = ds["data"].to_pandas()`
54
+
55
+ ## Responsible use note
56
+ 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.
57
+
58
+ ## Modeling notes
59
+ - Each row represents one hitter in one completed MLB regular-season game.
60
+ - Pre-event features include rolling hitter form, matchup history versus the opponent team, team context, and opposing-starter trend features.
61
+ - Outcomes include actual hits, total bases, RBI, runs, home runs, and threshold-hit flags for the completed game.
62
+ - The sample is meant to prove schema, coverage, and row meaning rather than replace the full dataset.
63
+
64
+
65
+ **This is a free preview.** Load it instantly, inspect the schema, and validate quality before purchasing the full dataset.
66
+
67

68
+
69
+ ## What This Preview Proves
70
+
71
+ - **Sample rows:** 8,391 (full dataset: 167,824 rows)
72
+ - **Columns:** 122 fields, fully described below
73
+ - **Format:** parquet (loads in pandas, HF datasets, or any parquet reader)
74
+ - **No authentication required** to load this sample
75
+ - **Schema and quality** are identical to the paid full dataset

89
+ ## Quick Start
90
+
91
+ ```python
92
+ from datasets import load_dataset
93
+
94
+ dataset = load_dataset("Karmane/mlb-same-game-parlay-hitter-trends-sample")
95
+ df = dataset["data"].to_pandas()
96
+ print(f"Rows: {len(df):,}, Columns: {len(df.columns)}")
97
+ print(df.head())
98
+ ```
99
+
100
+ Or with pandas directly:
101
+
102
+ ```python
103
+ import pandas as pd
104
+ df = pd.read_parquet("hf://datasets/Karmane/mlb-same-game-parlay-hitter-trends-sample/data/data.parquet")
105
+ print(df.head())
106
+ ```

109
+
110
+ ## Use Cases
111
+
112
+ - Compare which hitters historically clear hit, total-bases, RBI, run-scored, or home-run thresholds.
113
+ - Screen hitter rows by recent form, batting-order slot, opponent-team history, or opposing-starter context.
114
+ - Build time-aware notebooks that keep pregame hitter features separate from postgame outcomes.
115
+ - Filter by team, opponent, venue, or starter trends before building dashboards or exploratory models.
