Shaine Casas’ desire, immense talent and hard work continue to reward him.

The current member of the Texas A&M Swim Club, and former McAllen High standout swimmer, was selected to the 2019-2020 National Team, as USA Swimming announced its final roster Wednesday.

Casas earned a spot on the USA National Team in three events — the 100 back, the 200 back and the 200 individual medley. In the 100, arguably his strongest event, he qualified with a time of 52.72 seconds, which earned him a gold medal at the Phillips 66 National Championship, which was held July 31-Aug. 1. It was the seventh-fastest American time of all-time and the fastest time for an American teen — ever.

The 19-year-old Aggies sophomore’s 100 time is second only to Ryan Murphy, a three-time Olympic gold medalist and world-record holder in the men’s 100-meter backstroke. At the 2016 Summer Olympics, Murphy swept the backstroke events by winning gold in the 100- and 200-meter backstroke.

Murphy, 24, also sits atop the national team’s 200 back event with a time of 1:54.12. Austin Katz (1:55.57) is second and Casas (1:55.79) is third.

According to swimswam.com, which first reported the final roster for USA Swimming, the top six athletes in each individual Olympic event were selected, as determined by USASwiming.org’s world ranking from Jan. 1 through Aug. 25.

Casas also made the team in the 200 individual medley, claiming the sixth and final roster spot with a time of 1:58.83. Ryan Lochte is also on the team roster for the 200 intermediate. Lochte is a 12-time Olympic medalist, tied as the second-most decorated Olympian.
