KBO 2026 · 128 games in · Updated Sep 10, 2026

Samsung by ½.

128 games in. LG are 7.7 wins ahead of what their run differential says they should be; Hanwha are 8.3 behind it. The fifth and final October place is separated by 3½ games.

Moneyball Labs computes every advanced metric on this site from the KBO's own record book — wOBA, wRC+, FIP, WAR, run expectancy. Nothing here is copied from another leaderboard, and every assumption is written down.

Seven categories, one summer

In 2010 Lee Dae-ho led the KBO in average, home runs, RBIs, runs, hits, on-base and slugging — and homered in nine straight games, which nobody in the history of the sport had done. Recomputed against the league he actually played in, how big was it?

When is a bunt worth it?

A run expectancy matrix scaled to this season's KBO scoring, a bunt and steal calculator built on it, a Nash equilibrium solver for pitch selection, and a Markov simulator that plays any two clubs ten thousand times.
