As managers discussed instant replay prior to the season, they were generally circumspect, understated in their public comments. You got some eye rolls, and privately, some expressed concern, particularly with the challenge system.
Williams challenged an out call of Nate McLouth on a throw to first base, and the replay on the Nats’ broadcast appeared to indicate that the ball wasn’t quite in Freddie Freeman's glove when McLouth’s foot hit the base; in other words, McLouth appeared to be safe. You can see it here, over and over, because the challenge decision lasted four minutes. And McLouth was called out.
Williams was befuddled, as James Wagner of the Washington Post reported. From his story:
“I’m extremely frustrated by the process at this point,” Williams said. “Because if they’re seeing the same feed that we’re seeing, I don’t know how he’s out. I don’t know how Nate is out if they have the same feed that we have, so that’s frustrating because I thought he was safe. We’ve looked at it 100 times since then, and we believe he was safe. And if that is a safe call, then we maintain our challenge. … Again, I’m frustrated by the first one, though, because I see him as safe. And we have the same technology and the same video. I don’t know about that one. That frustrates me.”
Boston manager John Farrell was perplexed. “We had probably five angles that confirmed his foot was off the base, and when the safe call came back, it certainly raises questions on if they're getting the same feeds we are, the consistency of the system," Farrell said. "Yeah, it makes you scratch your head a little bit on why he was called safe."
What the managers want, above all else, is reliability, some degree of predictability. They don’t want to feel as though there is a roll of the dice when they’re issuing a challenge, and that they have no idea what the replay officials are looking at. They want to know that each challenge will be treated in the same way, with an expected outcome.
