MLB Head-to-Head Records: All-Time Series by Matchup

This hub publishes all 435 normalized pairings among the 30 current MLB clubs. Each matchup leads with its all-time record, from Retrosheet game logs through 2025 plus later final games. Recent form, streaks and season splits use completed final scores from the current feed starting in 2002.

The all-time record combines Retrosheet game logs through 2025 with later final games from the continuously refreshed feed, so it starts at the pairing's first meeting. Recent games, rate cards and betting context use the current feed from 2002. Each page states its source window so the record and the narrower analysis cannot be confused.

No, and we say so on every page. We hold no historical sportsbook prices for these games, so nothing here is an against-the-spread record or a closing-line result. What you get instead is outcome frequency: how often a pairing stayed inside one run, ended with a margin of two or more, or crossed a half-run total threshold. Those are facts about final scores rather than claims about old prices.

Treat it as historical context, not a prediction. Start with the series record, then compare the one-run share and scoring average with the recent 20-game sample. A visible difference shows how recent finals diverge from the longer archive. Starting pitchers, lineups, bullpens, weather and venue still matter more to the next game than this record does.

Each completed game counts once, including both games of a doubleheader when the source gives them separate game IDs. The 435 published pairings currently contain 60,034 meetings from 2002 onward. Spring training and games without a final score are excluded. Score or schedule anomalies are cross-checked against the official MLB Stats API before the matchup files are rebuilt.

The most recent published matchup data changed on September 25, 2026. This hub shows the newest data-change date across all 435 pairings, while each matchup keeps its own update date. A source check with no new or corrected final does not advance any public date. If a listed score or date looks wrong, send the matchup and game date through the contact page for source verification.
