Coming into the 2013 WSOP with a ton of momentum, Daniel Negreanu expected some big early results.
It hasn't quite worked out that way. We just three in-the-money finishes and a 12th his highest so far Negreanu's been held to just $20k in cashes.
Things are looking better in the $5k No-Limit Six-Max event that started yesterday, however, as Negreanu surged to a 168,600 stack, just off Jonathan Little's chip lead.
With 128 players left Negreanu still has a long way to go and will have dozens of notables in his way, but the signs are encouraging.
