Question : Where do the live scoring results on Google come from?

I noticed that if you google "PGA", it will show you the live scores for the current tournament.  I'm trying to determine where that data comes from, and how PGA got their scores to show up like that?

Answer : Where do the live scoring results on Google come from?

I would say part of your answer lies right within your post. The link below the scores show that the source is PGAtour.com. As to the how they got formatted like that, I would say that is Google's doing.
