Casas' swims in the 100-meter backstroke, 200-meter backstroke, and 200-meter individual medley were all qualifying times for the 2020 US Olympic Trials.

A little over a week earlier, Casas swam the unofficial fastest time swum by an American swimmer in history in the 100-yard individual medley with a time of 46.33 seconds at an intrasquad meet hosted by Texas A&M.

His start to the 2020−2021 swim season in late 2020 along with his performances before competition shutdowns related to the COVID-19 pandemic in 2020 earned him the Swammy Award for "NCAA Male Swimmer of the Year".

He was also chosen by NBC Sports as one of their top two picks for the 200-meter backstroke based on 2021 performances from U.S. swimmers in the race.
