Daniel Negreanu lost some more money to Doug Polk on Friday afternoon during one of the most up and down sessions played to date. Day 28 was full of big pots, but neither player could pull very far ahead.

Polk came into the day fresh off a commanding $119,000 win two days earlier. That winning session was his first out of the past six. On Day 27, he not only won big, but also killed his opponent’s momentum and made it difficult for Negreanu to eventually mount a comeback.

As the total hands played continues to rack up, Negreanu’s chances of winning become slimmer. He did nothing on Friday to improve his odds of pulling off a miraculous comeback and an improbable upset. But he also didn’t lose much — less than a full buy-in.
