if you had time to sit and prepare for the pitch, sure, but the video seemed to show the batter getting the info just before the pitcher goes into windup. There's not a whole lotta time to adjust to a pitch at the point, and thats where it can be detrimental to the batter rather then helpful. The only caveat is if the batter is sitting change up the ENTIRE AB and is told when one is coming, THEN he has a huge advantage. The only reason why I disagree is that if it didn't work very well or didn't help much at all, they wouldn't have kept doing it. That's where I wonder if the Astros were combining with scouting reports, ie they knew the WS pitcher threw hit-able change-ups, and thus were pinpointing that one pitch with the batter. In other words, telling their guys to sit change-up, and wait for the signal. They could expand that method to every team they play, every pitcher they face, by adjusting the batters expectations (ie sit change, sit FB) as they went. I mean, to me, its hard to lambast the level of dedication to win by using all sources available. I wish TheoCo would do that for KB, or better yet, Javy
