Jason Mercier opened with a raise to 2,000 and it folded to Phil Galfond's big blind. Galfond flung out a call and both players drew one card.
Galfond check-called a 3,400 bet from Mercier after the draw.
"Jack," said Mercier.
When Galfond announced that he had a ten, Mercier flung his hand to the muck and Galfond's was able to take the pot.
