OK...but I hope the club is tethered...
...because I'm no so worried about the ball as I am thinking of the comic cliche of the golfer who loses his grip (on the club) after the swing and it goes flying, and usually whacks somebody on the head. It usually happens on the backswing or at the end of the arc, and in both cases the club foes flying behind the golfer...in this case, that's where ISS will be.
I know, I know, I'm fretting the small stuff. But then, I never thought a Progress supply vehicle would ram into Mir, either. Excrement occurs, as the bumper-sticker says.
