After the first day at the Caesars Palace Classic main event, Ryan Young emerged as the chip leader.
He finished day one with 725,000 chips in front of him, more than 100,000 more than second-placed Sabyl Cohen, reports Card Player.
Other players to put in a strong early run included Carter Gill, Luke Staudenmaier and Eric Liu.
These gamers ended with 590,000, 520,000 and 470,000 respectively to make up the top five.
Gill sent a number of major competitors to the rail early on in the competition, including Roy Winston and Michael Mizrachi.
Other notable names who will not be back to play in the second day include Barry Shulman, John Juanda, Justin Bonomo, Barry Greenstein and Jason Mercier.
To date, Ryan Young has cashed in major tournaments on 25 occasions and finished first on three.
The American's most recent win came in March this year in the Spring Fever no-limit deep-stack competition, for which he earned $32,100.
