Here is the BTN video. Sequence is at about 33:15.
It’s awfully close, and then there’s a second or 2 where the video isn’t at a good angle. But I think 9/10 refs aren’t going to make that call unless it’s super obvious. DeAugustino did seem to realize his position and was rolling around.
Side note, but Illinois really screwed up by choosing bottom in the 3rd there, unless they didn’t care about the dual result and just wanted Renteria to get exposure to trying to get out from DeAugustino. It had been 5 minutes and DeAugustino couldn’t take him down, and you know he’s pretty tough on top (and probably the biggest 125 other than Glory). Then the final mistake was Renteria trying to go upper body in the last 30 seconds (edit: although I guess that was because he was trying to win the individual match).
Side note #2 - that was probably the most action I’ve ever seen from DeAugustino in neutral, presumably because he knew he needed the major. He’s usually incredibly boring in all the matches I’ve seen of his.
