This is an older play but I just came across it. The ball gets away from the catcher and the runner on third attempts to score. The pitcher covers home, gets the ball and tags the runner behind his back. Take a look.

The play was awesome especially given the context of the game (tied in extra innings). I would like to also give some kudos to the umpire. These plays are tough to get locked into because of the adrenaline of the moment.
In this play, the umpire calmly gets to the perfect spot on the field (third base line extended). He gets himself set – not moving at all when the play happens. He leans in to get a good look.
Then at the end he does not rush his call. Wild pitches usually wind up with a safe runner. But, the umpire did not let this or the odd tag by the pitcher sway him. Just a great example of home plate mechanics.
