What would be the ruling in the following situation? My buddy and I are not pros therefore we do our best to speed up play. I'm on the fringe and he's further away. I know I should have waited but I went ahead and hit the putt which would have ended either in the hole or real close. All the sudden his chip hits my rolling ball(his chip was too hard and my ball slowed his ball down). I ended up being much further from the hole and he ended up being a lot closer. In other words both balls are in motion. We both did not know what to do. I could not replace a ball that was in motion. So tell me please.What is the proper ruling in such a situation?
