That quote is from Ketel Marte, not Chourio, if that matters.
This issue of our hitters' use of ABS is frustrating for me. The Brewers pride themselves on getting an edge in every imaginable way since we will never be able to outspend teams like the Dodgers and Yankees. So why can't we be better at this aspect of it, given we're 100 games into the new system now?
To be clear, the split-second judgment of "Was it an incorrect call?" is very difficult. If players don't trust their own judgment, most of the time they should just accept the call and not challenge. I'm reminded of a Bunty at-bat early in the season where he looks at a called third strike that wasn't particularly close to being a ball, then compounds his problem by wasting a challenge on it. It was early in the game, too.
But there is no excuse at all for Chourio's miss on the last strike of regulation. Even if he's wrong, we still have one left in extra innings. It is no longer a question of "Are you certain?" and more a question of "What have you got to lose by being wrong?" In this case, he wasn't losing much and would have gotten the challenge correct. But these are things that should be taught to our hitters - that the timing of the challenge matters greatly! And the rules are strict that you can't coach from the dugout in those situations, you can absolutely remind someone in the on-deck circle that we have two challenges left in the bottom of the 9th and if it's close at all, don't be afraid to try it! And yet, our boys seem lost on when to challenge and when not to. Chourio clearly discussed it with someone after that game, because he incorrectly challenged in his first at-bat the next game!
Coaches... Murph... tighten up the ship here!
