How to read this page

▶

A player page shows one box score, because a hitter and a pitcher share almost no column — which half you get follows the one he appears in. Every rate is built from summed counts, so a batting average is hits over at bats across whatever window you picked rather than an average of nightly averages. Pitchers rank against starters or relievers, which is the split the sport itself draws. A dash means no number for that cell, or a zero in a roster column that counts.

Seattle Mariners

2026 · Regular Season

NotableSeattle Mariners place 2nd of 30 teams in walks allowed, at 441.

1 is best, whichever way the stat runs — a defensive row at 1 allowed the fewest. The count after each slash is how many teams were placed; a rate skips those with too small a sample. Red to green by where the placing sits. A stat with no better end is left unpainted.

About MLB Research

▶

Every number the site holds for a Major League team and the players who played for it, in one place. Pick a club, a season and a set of games, and read it. Nothing here needs an account.

Where the numbers come from

The same tables the boards read, resolved through one shared definition per stat. A rate is computed over the whole window rather than averaged across games, so a season figure is not the mean of the nightly ones.
