Chris Brewer opened to 100,000 on the button and Adrian Mateos three-bet to 375,000 from the small blind.
Brewer four-bet to 750,000 and Mateos five-bet jammed. Brewer snap-called for 2,375,000.
The board came and Brewer doubled up.
"Always a sweat," said tablemate Nick Petrangelo as Brewer moved into the tournament chip lead.
