Regardless of how close the pitches might have been, they highlight why I’m in favor of robo calls of balls and strikes. As long as they are close to as accurate as the human umps, it will remove the “human element” that includes umpires favoring certain pitchers or hitters (subconsciously or otherwise) or doing a Frank Drebbin imitation to thrill the home fans. Balls and strikes shouldn’t be affected by umpires having different strike zones or a catcher’s ability to frame pitches to make balls look like strikes.
When technology exists to improve officiating, why not take advantage of it? Think of electronic timing systems in things like Olympic swimming that can detect when a swimmer touches the wall instead of relying on human eyes to decide who touched a thousandth of a second sooner.
