Mine was righty with minor switch until 14 then began to switch. Really focused on lefty last year when preparing for college and knew as a LHP and DH they would not want to show left shoulder to RHP's in SEC. Has swung 95% this summer leftie. it takes a lot of work to be successful. What is logic? If logic is just to do it then total waste of time and energy. Become a great rightie.
I agree. Most of the top hitters in mlb are currently righties. Trout, Betts and miggy did ok as righties.
There currently is a trend in Latin America towards switch hitting and many young good Latin hitters are switch hitters (lindor, Jose Ramirez, wander Franco, albies) but those kids have basically unlimited practice time.
