iPad. Keep score of the game with Scorepad, comes in handy for stuff like this.
But so they blew the call, I get that. The ball was at the back stop. He swung, and thus there was no tag/control of the ball, or they thought it was a foul. I don't understand how the umpire could explain how that was possibly, in any conceivable way an out from my seat behind the nats dugout. From here it just didn't look like there was any way it could be an out with the ball still sitting at the net while they were arguing.
