Austin Katz was one of the top high school swimmers in the country at his time. He swam for the Sarasota YMCA Sharks, and was a multi-time YMCA National champion. From April 2015 to April 2016 he dropped his 100 back from 48.28 to 47.23 and his 200 from 1:43.70 to 1:41.48. As a No.6 recruit in the Class of 2017, Katz committed to swim for the Texas Longhorns.
As a freshman in college, Katz was a part of four winning relays at the Big 12 Championships. He won both of the backstroke events and broke the Championship Record in the 200 backstroke with a time of 1:39.10.
At the NCAA Championships, Katz scored 35 points and helped Texas win its fourth consecutive team title. He placed fourth in the 100 backstroke breaking the 45 second mark by 0.01 seconds. On the last day of the meet, Katz won his first NCAA Championship title in the 200 backstroke in front of his team mate John Shebat. Katz entered the final with the fourth fastest time but he managed to drop 1.31 seconds and take the title in 1:37.53.
Katz started the 2019 NCAA Championships by helping Texas to a national title in the 800 free relay, splitting 1:31.45 on the 2nd leg to aid the horns in breaking the NCAA, American, and US Open record. After initially finishing 16th in the 100 back with 45.39, Cal sophomore Daniel Carr bumped him to 17th after swimming a 44.86 in a re-swim. In the 200 back, Katz and teammate John Shebat went into finals seeded 1-2, and came out of finals finished that way as well. Katz went 1:36.45, annihilating his best time and touching in 2nd by a margin of .03 behind Shebat, making Katz the 3rd fastest performer in history in the event.
