Buster Posey safe at home plate on tag play? (Video)

Was Buster Posey really safe at home plate on a tag play to end the top of the 9th Saturday?

The San Francisco Giants were trailing the Washington Nationals 1-0 entering the 9th inning of Game 2 of the NLDS at Nationals Park. Joe Panik got a two-out walk, so the Nats pulled starter Jordan Zimmerman for Drew Storen. Buster Posey got a hit to put runners on first and second for Pablo Sandoval, who hit a two-out double down the left field line.

Panik scored to tie the game, but Posey was thrown out at the plate. The Giants asked for a review of the play, and the call was upheld.

Take a look at this screenshot from our friend Cork Gaines, who believes it’s proof Posey was out:
