The ball landed 398 ft from the plate, down the left-field line, where the wall is 350 ft. The outline is this park’s wall; the dashed line is the ball’s path over the ground.

Would it be out in every ballpark?

Each park’s outfield wall is sampled at seven spray angles and interpolated to this ball’s -36.6° angle, then compared against its 398-foot projected distance. On that basis it clears the wall in 30 of 30 parks.

That is a no-doubter: there is no outfield in the league deep enough to hold it at this angle. Distance here is Statcast’s projected distance from the MLB Stats API — where the ball would have landed unobstructed. Wall height and the ball’s trajectory arc are not modelled, so a ball that clears on distance might still have hit high off a tall wall in a park that has one.
