A bowler "pounds" a rosin bag on his ball at the ball return prior to bowling. This creates a lot of rosin on his ball about the thumb and finger holes, and literally on about a third of his ball surface. (Assuredly some is also falling on the floor as well).
He then wipes his hand over the top of the ball (by the thumb and finger holes), and then wipes his hand on his slide sole of his shoes.
Several bowlers have questioned this, as since he does not use a towel to wipe off the ball, there most likely rosin being transferred onto the lane. But the bigger concern is some feel that he could be altering the approaches, or creating an issue for others with rosin on the floor.
Personally I could care less other than possibly being a safety issue of others slipping or sticking on the approaches.
I greatly appreciate any insight, rules, etc.
