It's hard to second-guess a player in that situation. Nobody's in a better position to decide whether to swing or not than the player himself. Especially when that decision is made in the micro-second that the pitch is already en route. And perhaps, Alvarez was leaning towards taking the 3-0 pitch before it was ever thrown anyways, but when the pitch came in, suddenly decided that it was a meatball that he could crush. And of course, Mendoza agreed. Otherwise, he would've sent Alvarez the "take" sign. (Unless he did, and Alvarez ignored it). According to today's Athletic piece on the Mets, Alvarez was given the green light on that fateful 3-0 pitch. https://www.nytimes.com/athletic/5711178/2024/08/20/mets-francisco-alvarez-walk-off/https://www.nytimes.com/athletic/5711178/2024/08/20/mets-francisco-alvarez-walk-off/ Also, Alvarez's health is apparently not the issue causing his current slump. According to hitting coach Eric Chavez, Alvarez had developed the bad habit of trying to pull most everything for Home Runs.
