I don't mean guessing in a bad way. It's an educated guess, based on year of experience. There's no way to know if the ball did or didn't go over the bag from where he was standing. He's backing away, sees the ball coming toward him, years of experience tells him it's going to continue to curl foul, and he makes the call. But yeah, it's a guess.

But from the video I've been watching, it bounced fair both before and after the bag. Simple geometry will tell you it passed over the bag, right? But given the same circumstance, I would have probably called it foul too.
