Six by Four

Every contact hitter is climbing the same cliff. The hands get too good at finding the ball. The swing decelerates. The power drains. Kwan, Arraez, McNeil, and Hoerner all climbed it. Nobody named it. Until now.

Power hitters whose swing plane gets too steep create a hole beneath their hands. Offspeed pitches win. Rhys Hoskins whiffs on 54.3% of offspeed. Jimmy Crooks leads baseball with a Steeps Score of 86.1. The tools are real. The plane is the problem.

Combine both failure modes into one mechanical health score. Correlates with OPS at -0.587, outperforming bat speed, exit velocity, and hard hit rate individually. Jackson Chourio at 20 years old is the most mechanically perfect hitter in baseball.

Jimmy Crooks scored 86.1 on The Steeps in the MLB. He also appeared on the MiLB callup candidate list. The minor league dataset doesn't measure attack angle or bat speed. Coaches are working on the wrong thing. The data to fix it has always been there.

Two dimensions. Four inputs each. The first systematic framework for telling a hitter precisely where to stand in a 24 square foot box, accounting for their Contact Cliff score, Steeps score, contact point spread, and bat length. The sport has never done this.
