Correct and right call by the ump. If a ball rolls into fair territory before it crosses the corner base, it is still fair. Likewise, if it rolls into foul territory after it crosses the corner base in fair territory, it is still a fair ball.

The Dodger catcher made a real heads up play by going for the ball while it was still moving in fair territory. Had he allowed it to roll foul again, there would have been no play. What I found really amazing is that the Seattle players and the batter all froze after the ump made the fair ball call.

They would probably have been out anyway, but back in the 60's or 70's, the player would have been fined by the team for at least not trying to advance.

The Padres weren’t very mobile either :)

I was watching the game, and you are bang on about the catcher making a heads up play.

it appeared as though he started to pick it up in foul territory, but saw the potential for a multi-out play and let it roll.

for whatever reason, he waited for it to go fair before he pounced on it, and directed the infielders to throw the ball back across all three bases.

Correct and right call by the ump.
From your perspective. But the ump put both his hands in the air which means foul ball and that's what all the runners saw.
Also, we don't know what, if anything, the ump called verbally. Did he yell "foul" as he put his hands up?
