Any tips for consistently shooting with follow through?

Watch Ken Griffie Jr and his follow through.
Ichiro had a unique uniform adjustment as his pre pitch routine.

I really appreciate the analogy because I used to play baseball through high school and adult league in my 20s and 30s. Ken Griffey Jr had one of the purest swings baseball has ever seen. Im not sure how to incorporate that into my pool stroke though.
