The other night I was watching a match online and the shooter was running the colors at the end of the game. He was shooting the green and scratched. The green he was shooting went down table about where the pink would spot. His opponent was awarded "free ball" and was able to shoot another color for the same value as the green. Could someone explain why he did not have to shoot the green (which would have been a much more difficult shot than the duck he shot for free ball)? Why did his opponent get free ball? Thanks for your help.
