The F5 line ladder

Isolate the starting pitchers
The first 5 innings are the starters' territory, before the bullpen. The file joins Full-Game and Modeling Features on game_pk.

fair_over = p_o / (p_o + p_u)Every price is timestamped. Captured before first pitch.
Every row carries the exact time of the snapshot. Every snapshot was checked against the official first-pitch time published by MLB: we keep the last one strictly before the actual first pitch, never more than 96 h earlier.
2023 starts on May 3, 2023: Pinnacle F5 was not captured before. These are pre-match prices, not closing lines — and we do not claim otherwise. Lead time varies by season: filter it yourself with the timestamp.
The 2026 season starts on 2026-04-12: from March 25 to April 11 the captured prices were corrupt (both sides ≈ 1.02) — we dropped them rather than ship them.

Before you buy
Is this the closing line?
No, it is the last price captured before first pitch, timestamped. In 2023-2025 half the snapshots fall within ~10 min of the game; in 2026 earlier (~1.6 h). Do not pool both periods without controlling for lead time.
Is the 2026 season complete?
No: 2,210 of the 2,429 regular-season games, from April 12, 2026 (the 218 earlier games had corrupt captured prices and were dropped). The season is over: this is the final file.
What is the ProbWin layer?
Added at the end of each row without changing the other columns: the fair probability (both Pinnacle prices, margin removed), the best closing price among tracked bookmakers on the same line (last snapshot before the real first pitch, at most 6 h before), its bookmaker, the gap to the fair price and the bookmaker count. On a tie, the bookmaker shown is Pinnacle. Rules and a measured truth test in the README.
How do I get the file?
Right after payment a download link appears on screen and is emailed to you. The archive contains CSV and Parquet files plus a README documenting every column.
Can I use it in a commercial product?
Yes for your models, analyses and tools, commercial ones included. Reselling or redistributing the files themselves is not allowed.
