I'll note that Duda became the heavy favorite going into the Blitz rounds, since his Blitz rating of 2812 placed him at World #7 in blitz. According to the FIDE live ratings site, in FIDE classic ratings Jeffery Xiong (2716.1) has leapfrogged Sam Shankland (2702.0) as USA #5 rated behind the "Big Four".

Why do you guys always spoil the freaking results in your headline? I was so happy to sit down after work and watch the stream but now it's ruined. And I get the article in my feed on my phone so I couldn't avoid it.
