Jazz absolutely could have made a bad throw. But that’s a bad reason to send a runner.
Using StatCast numbers, Eaton runs 29.7 feet per second. Lets cal it 30. He was exactly 90 feet from home when Jazz got to his feet. Three seconds to home . If Jazz looked to first and decided not to throw and took a full second to do so, Eaton is 60 feet from home plate.
Oer StatCast, Chisholm thrown 82.3 mph, which is about 120 feet per second. He was probably 130-135 feet from home, so the throw home takes just over a second. Again, if he decides he has no play at first, Eaton would have been out by almost 25 feet. And that’s with Jazz holding the ball for a full second, which is unlikely. He had almost another second to make up his mind.
Kerkering panicked. Kim was running on contact from maybe 75 feet away. Pages was unraveling from his swing and then running just over 90 feet. He has been taught since high school (hopefully) “know where you’re going if the all is hit to you.” He messed up on multiple fronts…
