"I don't know how I'm talking right now, I'm kind of speechless," Shlez told the Borgata Blog. "It means a lot, but I don't know what it means yet because it hasn't sunk in yet."
At one point Shlez was down to just 11 big blinds at the final table, but managed a miraculous comeback.
It all started when he picked up pocket kings and picked off an ill-timed shove by third-place finisher Trevor Savage.
