Did you see their lift during the warm up? I’m not an expert, but that one looked easy to me. I agree that the one in the program looked rough.
No, unfortunately, I couldn't grab a livestream, so the only evidence I can cite is the video that was linked above.
Maybe the problems were an aberration, as you suggest. Maybe nerves?
But the elements in the program itself looked as through they need more strength on his part.
