Tiger two shot penalty for today or do they change his score from yesterday?

This would suck if you took any kind of bet for Tiger yesterday at or over par and they hit him with the 2 shot penalty and change his score for yesterday... don't follow golf a lot anyone tell me how they score that?

I believe it would be a loss as his correct scorecard is a 73.
