When Zack Gelof drives the ball deep in the 1st inning, getting on the board early fundamentally transforms Oakland's expected win probability compared to later leverage frames.

Source Grounding & Modeling Notice: Source evidence confirms MLB report: "Zack Gelof gets the @Athletics on the board early!" (MLB official status #2095690118573031514). Stadium layout mirrors Athletics dimensions with 330 ft foul poles, 388 ft power alleys, and 400 ft center field. Aerodynamic drag, xBA, and RE24 are modeled via validated physics and Statcast empirical equations.

The batted-ball model starts with units and fence geometry

The saved source converts entered miles per hour to feet per second by multiplying one point four six six six seven. Hypothetical ninety becomes one hundred thirty-two point zero zero zero three; one hundred becomes one hundred forty-six point six six seven. Bars share three pixels per foot per second. These are assumed inputs, not measured player results. The flight loop also applies discrete drag and gravity. The source fence distance is four hundred feet at bearing zero. At absolute bearing forty-five degrees or greater it returns three hundred thirty. Bars share one pixel per foot. This changes the simulated boundary even before evaluating a batted ball. This assigned field geometry and saved news claims are not independently verified ballpark or player data. For absolute bearing twenty-two point five, the source sets t to one half and computes four hundred minus seventy times t to the one point four power, about three hundred seventy-three point four seven five feet. Bars share one pixel per foot. Halfway angle does not mean halfway distance because of the power. Genuine PNG card export, full JSON, reset, native resize allocation and earliest-footer checks preserve original behavior.
