Day 1D of the Main Event was a huge one and saw the record 8,773 field of 2006 fall and ended with 3,202 players with chips at the end of the night.
After all the bags were collected and bagged there was a familiar name at the top of the chip counts, Nicholas Rigby of Pittsburgh who had his Main Event moment in the sun back in 2019 when he made a run to a 52nd place finish. He gained attention on the live stream coverage back then with very aggressive play and the famous “dirty diaper” hand of three-deuce off suit which he used to win several pots back then.
It’s safe to say this aggressive no fear style is still working for him in this deep stacked event as he bagged up 408,800 which is the largest stack across all Day 1 starting fields and the 2nd largest Day 1 stack since the Main Event increased starting stacks to 60,000 in 2019. (Largest was Bryan Campanello with 417,500 in 2019).
