Labra did not look great but it should also be mentioned he was one of the last qualifiers even with his conversion (maybe the last?). He was unlikely to ever make it through.
Troutner finished about as expected, would've likely made it in a fast race and had the 2nd-fastest close in the heat but ran with poor tactics and couldn't make up the distance.
And Sahlman looked pretty much as expected, comfortably got the big Q right behind Houser.
So basically the exact same results we would've expected if they had run their times at sea level. No big blowups, nobody looked out of their depth, Labra just had an underwhelming close (expected for the last qualifier), and Troutner didn't run a smart race.
