Is there a rule governing what a bowler can do with his off hand? Is it illegal to hold a towel or something in the non-bowling hand during a delivery? It came up in our league, and someone said it was illegal, but couldn't reference the rule, and I can't seem to find it, either. Maybe I'm using bad search terms.
