What makes you a better hitter is getting a pitcher's tendency, or you see the infield moving early or maybe even the catcher tells you what's coming, because it would be very difficult to look for a light and then also on the release point. It's a lot easier as a runner at second base to relay signs or locations, but you can't even see the signs sometimes from second base. And lights from center field? That's not the case here.
