ABOVE AVERAGE IS OVER:
Turns out robot umpires have one big flaw: They're too perfect (Joseph Bien-Kahn, Sep 27, 2023, Business Insider)
Though robo-ump is sold as a more accurate future through technology, it's also another paradoxically progressive change that sets out to restore the game to the more action-packed glory of yesteryear. The MLB league official says they hope that a shrunken, more consistent zone will decrease strikeouts and walks and will lead to more balls in play. Unfortunately, so far this year, Hawk-Eye's ABS has added many more walks than the number of strikeouts it has removed. Those results are disappointing, the league official tells me, to say the least.Founded by Paul Hawkins, who has a doctorate in artificial intelligence, in 2001 -- the same year the iPod arrived -- Hawk-Eye was originally conceived as an optical-tracking tool to enhance TV sports coverage. The first broadcast partner used it for cricket. But then, in 2006, Hawk-Eye became an official replay tool used by the tennis judges. Sony bought the company in 2011 for an undisclosed sum. Soon, English Premier League soccer, NASCAR, the Olympics, the Rugby World Cup, and golf's European Tour were using Hawk-Eye in broadcasts and to increase the accuracy of human refs. Hawk-Eye had 12 cameras perched in all 30 MLB stadiums by opening day 2020, marking a watershed for the American market. The NFL began using Hawk-Eye to aid with replays the next year, and the NBA just signed a multiyear deal with Hawk-Eye this March.Umpires 2Hawk-Eye's "average error is about 3 millimeters, less than the width of an M&M," says Goltz. That level of accuracy has already leapfrogged humanity's limits. Tyler Le/InsiderAs I connect with Justin Goltz, Hawk-Eye North America's commercial director, he can't get his camera working on Zoom. A former college pitcher, Goltz says he's sure he'd be against ABS if he still played, because "the ambiguity of the strike zone probably works more in your favor" as a young pitcher without pinpoint control. "But as someone who now understands the nuances of the business of sports and baseball and the way they're trending with legalized gambling and betting and objectivity playing a big part in making the game as fair and as accurate as possible, I'm a firm believer that it's a step in the right direction," he says. (The MLB league official tells me that legalized gambling has not been a factor in implementing ABS.)"The technology is there," Goltz adds, explaining the intricacies of Hawk-Eye's ball-tracking system, which uses high-performance cameras to triangulate an object's trajectory. "Our average error is about 3 millimeters, less than the width of an M&M." That level of accuracy has already leapfrogged humanity's limits. But even Goltz acknowledges there's still the issue of what zone all his company's technology is legislating."There are additional layers to the problem that need to be solved," he says. "How do you define the strike zone? Is it on a per-player basis? Is it a standard strike zone? Is it an oval-shaped strike zone? Is it a square-shaped strike zone?" Goltz explains that MLB is taking the lead in answering those subjective questions; Hawk-Eye just delivers the data.
There's a curious phenomenon now where prospects are said to have "gamed" the robo-ump to get a good bb/strikeout rate. Then when there are real umps at the next level they strike out more. Essentially, they are being punished for knowing the strike zone better than the guys behind the plate.
