is this a result of a roundhouse right shoulder ? this is the strangest ball flight i've ever seen starts left and then high right turn..happens 1 ball out of 20

I would say yes. You may have too much pivot trying to turn the shoulders way too soon. Think baseball and hit a hard liner to the second basemen while trying to hit the pitcher with the bat. Violent stuff but the right direction of the clubface and hands.
