College (Texas A&M)
Casas made a difference his first year as an Aggie. At the SEC Championships, he placed 4th in the 200 IM (1:43.35), 7th in the 100 back (45.94), and 2nd in the 200 back (1:39.84).

2019 National Championships
The 2019 Nationals were a breakout meet for Casas, as he posted a best time nearly every finals session he got in the pool. On days 1 and 2, he won the C-final of the 100 free in 49.17 and placed 2nd overall in the 200 back (1:55.79), missing the top of the podium by just .07.
