Cary Katz raised to 225,000 from the under-the-gun position only to have Connor Drinan three-bet to 580,000 from the big blind. Katz responded with a four-bet to 2 million. Drinan then moved all in and Katz called off for 5.79 million.
The flop gave Katz a freeroll to hearts, and the turn made it a very real possibility.
"Oh my god," someone at the table said as the crowd moaned realizing one more heart would give Katz the massive pot.
The river then shot shockwaves through the crowd. Sam Trickett and Antonio Esfandiari could not believe what happened and walked away from the tabled shaking their heads, while Katz and Drinan remained seated as the floorman and dealer sorted out the stacks.
It was the worst bad beat in the world's biggest tournament and Drinan, who qualified for the tournament via a $25,000 satellite, was the unfortunate victim. The stacks were verified, and as it turned out Drinan had started the hand with slightly fewer chips.
"I'll never complain about having aces cracked again," Katz said after Drinan had exited the stage.
