I'm an older player(50) who has just started playing men's modified fastpitch. Because you can't windmil,the speed is less,but many pitchers can still bring it. My main problem is hitting changeups. The ball looks the same to me after release,whether a fastball or not. I like to be aggressive and I look to hit every pitch,unless I see it's out of my zone,but I'm having trouble judging the speed of the pitches. I try to keep my weight back but sometimes I still struggle. Can anyone give me some tips?
