The Ukranian Born poker pro took home the $533,210 first-place prize beating New Haven, Connecticut's LJ Sande heads-up.
"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.
"I don't know how I came back," he said. "At that point it seemed dim, but I never lost confidence in my decisions and in myself."
2009 WPT Southern Poker Championship runner-up and high-stakes circuit regular Bobby Suer was the best know player at the final table, but failed to finish better than fourth.
The $3,500 event began Sunday drawing 718 players to the Borgata Hotel & Casino to create a $2,369,400 prize pool.
Here's how the final table finished up:
1 Vadim Shlez $533,210
