I was at the driving range today and am right now watching the baseball World Series, and the following occurred to me;
Why is it that in golf it is of paramount importance to keep the left arm straight, while in baseball the left arm is bent? (That’s for righties, and the opposite for lefties.)
Yes there are differences in the requirements - the golf ball is on the ground and stationary, while the baseball is about at waist level traveling past you, and the club is longer than the bat. But there are also many similarities. I have even seen golf instruction videos pointing out important steps in the golf swing and noting “just like a baseball swing”.
So why can’t a successful golf swing employ a bent left arm? Or for that matter a baseball swing with a straight left arm?
