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). At the NCAA Champs, he switched up his event lineup and still had success, placing 13th in the 200 IM (1:42.71), 25th in the 100 fly (45.98), and 11th in the 200 fly (1:41.31).
After a breakout summer, Casas wasted no time converting his success over to short course. At the Art Adamson Invite in December of 2019, Casas dropped best times in several events, including the 200 IM (1:40.16, fastest teenager ever), 100 back (44.48, school record), 100 fly (45.26, school record), and 200 back (1:38.21, 7th fastest performer all-time).
At the SEC Championships, Casas started things off by helping the Aggies to a win in the 200 medley relay, the mens team’s first ever SEC relay title. On day 2, Casas kept the train rolling, taking the SEC title in the 200 IM at 1:39.91, becoming the youngest man to ever break 1:40 in the event. After taking a 2nd place in the 100 back (44.68), Casas blew away the field in the 200 back, touching at 1:37.20, becoming the #5 performer all-time and breaking Ryan Lochte’s meet record in the event from 2005.
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. On day 3, he once again won the C-final, this time in the 100 fly (52.15). On day 4, Casas won his first senior national title, touching first in the 100 back by over a second at 52.72. On the final day, he placed 2nd once again, this time in the 200 IM (1:58.83).
