Bryan Piccioli leads the final 251 players in the WSOP Main Event

LAS VEGAS -- The dust has settled in the Amazon Room as Day 4 of the 2016 World Series of Poker draws to a close. Just 251 players remain in contention for poker's most illustrious prize. Leading the field heading into Day 5 is bracelet winner Bryan Piccioli, who bagged a stack of 4,026,000 at the Rio All-Suite Casino & Hotel.

Piccioli is no stranger to success on the WSOP felt, winning the 2013 WSOP-APAC in the $1,100 No-Limit Hold'em Accumulator event for his first gold bracelet. Piccioli began rapidly climbing the ranks late in Day 4 to seize the chip lead. He was seen bullying his opponents during the last level to climb over the three-million chip mark. Piccioli eventually crossed the four-million chip mark and was the only player to do so by day's end.

Other top stacks at the end of Day 4 belong to Thomas Miller (3,684,000), Farhad Jamasi (3,380,000), Daniel Zack (3,085,000), and Tom Middleton (3,025,000).

Daniel Colman, who famously won $15,306,668 in the 2014 Big One for One Drop, surged toward the top of the chip counts late in the night after doubling through Brandon Adams. Colman is searching for his first WSOP cash of 2016 and looks to add to his more than $17 million in WSOP earnings. He finished the night with 3,711,000 in chips.
