He played college baseball for the Vanderbilt Commodores and was selected by the Rangers with the second overall pick of the 2021 MLB draft. He made his MLB debut in 2024 after rising through the minor leagues as one of the top pitching prospects in the organization.

Early Life and Background
Jack Thomas Leiter was born on April 21, 2000, in Summit, New Jersey. He grew up in a baseball family and was introduced to the game at a young age. Leiter attended Delbarton School in Morristown, New Jersey, where he starred on the baseball team and was teammates with future big leaguer Anthony Volpe.
As a senior at Delbarton in 2019, he was named the Gatorade Player of the Year for the state of New Jersey. At the time of his high school selection, he was 6–0 with a 0.54 ERA on the mound while also batting .364. Leiter was considered a top prospect for the 2019 MLB draft, but his strong commitment to Vanderbilt University caused him to slide to the 20th round, where he was selected by the New York Yankees but did not sign.
Earlier, in July 2018, he played in the Under Armour All-America Baseball Game. In December of that year, he represented the USA Baseball 18U National Team at the 2018 COPABE Pan-American Championships in Panama City, helping Team USA win a gold medal.

He was named the Southeastern Conference (SEC) Co-Freshman of the Week for the performance before the season was cancelled due to the COVID-19 pandemic.
As a redshirt freshman in 2021, Leiter returned to Vanderbilt’s starting rotation. On March 20, 2021, he pitched a no-hitter in his SEC debut against South Carolina, striking out 16 batters. In his next start, he pitched seven no-hit innings against Missouri. He was named the SEC Newcomer of the Year and a consensus first-team All-American, helping lead Vanderbilt to the 2021 College World Series finals.
