In 2021, he garnered national attention by throwing a no-hitter against South Carolina, compiling 16 strikeouts in his SEC debut, and was named the SEC Newcomer of the Year. His dominant college performance led the Texas Rangers to select him as the second overall pick in the 2021 MLB Draft, signing him for a substantial $7.92 million bonus.
Leiter's professional journey began in 2022 with the Double-A Frisco RoughRiders, where he posted a 3-10 record with a 5.54 ERA over 92.2 innings. His struggles continued into early 2023, including a period on the development list to refine his mechanics.

His strong performance in Triple-A led to his much-anticipated MLB debut with the Texas Rangers on April 18, 2024, against the Detroit Tigers. While he recorded his first MLB strikeout on the first batter he faced, his debut was challenging, as he allowed seven earned runs in 3.2 innings.
