HARLINGEN, Texas (KVEO) — Former McAllen High School and current Texas A&M swimmer Shaine Casas finished third in the 100-meter backstroke final on Tuesday.

Casas lead the group at the turn, but three-time gold medalist Ryan Murphy overtook Casas to finish with a time of 52.33, followed by Hunter Armstrong in second at 52.48. 

The McAllen native placed third with a time of 52.76, missing his first chance at qualifying for the 2020 Olympic games.

Casas will compete in two other events, the 200-meter backstroke and the 100-meter fly in hopes of qualifying for the games.

The 200-meter backstroke preliminary qualifying will take place at 10:22 a.m. on Thursday. The 100-meter fly preliminary round will be at 11:01 on Friday. 

On Monday, Casas advanced to the final round in the 100-meter backstroke at the U.S. Olympics Swimming Time Trials.

Casas finished third overall with a time of 52.77 seconds, behind Hunter Armstrong at 52.67, and Ryan Murphy, at 52.22 on Monday. 

Swimming experts predicted Ryan Murphy and Shaine Casas to win the top two spots in both the 100- and 200-meter backstrokes, sending them to the 2020 Tokyo Summer games.

Casas has tallied seven individual A-cut times in five different events, lowering his own school record in the 100 back, 200 back, 200 fly, and 200 IM. Has also been named SEC Male Swimmer of the Week on four occasions, according to Texas A&M.

Most recently, Casas began his junior season with a school-record performance in the 200 back, claiming additional top-two finishes with A-cut times in the 100 back, 400 IM.

Cases is scheduled to swim Tuesday at 7:44 p.m. For a schedule of the next swimming time trials click here.
