You're chasing cause you're trying to hit every pitch that's thrown. Instead, try focusing on recognizing pitches only to the center of the strike zone and adjust once you have two strikes. Once you get used to not swinging at pitches not to the center, your discipline to swing at good pitches will get better. I also lay off breaking and off speed pitches early in the count because for me, I'd rather hit a fastball in the sweet spot. BTW, I play with zone hitting with the PCI on and on veteran mode.
