How to Use Player Matchup

Start typing any active MLB player's name in each search box above. We'll pull their current-season stat line from the official MLB Stats API and re-express it in sabermetric terms so you can compare apples to apples, whether you're lining up two hitters, two pitchers, or two versions of the same player across seasons.

What the comparison shows

  • For hitters: wOBA (weighted on-base average — the gold-standard one-number measure of offensive value), wRC+ (park- and league-adjusted run creation, where 100 is league average and 120 is 20% above), ISO (isolated power, i.e. slugging minus batting average), BABIP (batting average on balls in play, a luck/contact quality indicator), and K%/BB% for plate discipline.
  • For pitchers: FIP (Fielding Independent Pitching — what ERA would be if defense were league-average), xFIP (FIP normalized to league HR/FB rate), K% and BB%, BABIP against, and raw innings-pitched workload.

Sample size matters

Be careful comparing players before they've stabilized. Hitter K% stabilizes around 60 plate appearances, BB% around 120, and wOBA around 300. Pitcher K% takes about 70 batters faced, while BABIP for either side can remain noisy all year. If a player has fewer than ~100 PA (or ~40 IP for a pitcher), treat wild outliers with skepticism — the luck component is still large.
