About Chasing .400
Most stat sites answer "who leads MLB today?" This site answers a better question: who is on a historic pace, how far from immortality are they, and what exactly must happen from here?
The math, shown in full
Every number on this site comes from simple, explainable formulas. Projections default to team-game pace: current total ÷ team games played × 162.
Consecutive hits to reach .400 now: ceil((.400 × AB − H) / 0.6) Hits needed over the next N at-bats: ceil(.400 × (AB + N) − H) Projected full-season AB: AB ÷ team games × 162 Rest-of-season hits to finish .400: ceil(.400 × projected AB) − H Counting-stat pace: total ÷ team games × 162
Feasibility labels
On pace — projection meets the target. Near pace — within about 8% of it. Long shot — reachable with a modest acceleration. Extreme — requires a historically implausible run. Impossible — the math has closed the door this season.
Record modes
The brand is anchored to Ted Williams' .406 in 1941 — the last .400 season in the AL/NL. The official MLB record book now also includes Negro Leagues seasons, led by Josh Gibson's .466 in 1943, so record pages show both views.
Data
Player and team statistics come from MLB's public Stats API; pitch velocity, exit velocity, and launch angle come from Baseball Savant (Statcast). Snapshots are taken once daily after all games are final; the timestamp on every page tells you exactly how fresh the data is.
