Professional career
Tampa Bay Rays
The Tampa Bay Rays selected Liberatore in the first round, with the 16th overall selection, in the 2018 Major League Baseball draft. He signed with the team for a $3.5 million signing bonus. He was assigned to the Gulf Coast Rays of the Rookie-level Gulf Coast League. After posting a 0.98 ERA in eight starts, Liberatore was promoted to the Princeton Rays of the Advanced Rookie Appalachian League. He pitched in one game for Princeton to close out his first professional season. Liberatore began the 2019 season in extended spring training before he was assigned to the Bowling Green Hot Rods of the Class A Midwest League on May 15, with whom he spent the remainder of the year. Over 16 games (15 starts), Liberatore went 6–2 with a 3.10 ERA, striking out 76 batters over 78+1⁄3 innings.
St. Louis Cardinals
On January 9, 2020, Liberatore was traded to the St. Louis Cardinals (along with Edgardo Rodriguez and the Rays' Competitive Balance Round B Draft Pick) in exchange for José Martínez, Randy Arozarena, and the Cardinals' Competitive Balance Round A Draft Pick. He did not play in a minor league game in 2020 due to the cancellation of the season due to the COVID-19 pandemic. For the 2021 season, Liberatore was assigned to the Memphis Redbirds of the Triple-A East.
In late May, he was placed on the temporarily inactive list while he competed for a spot on the United States national baseball team, in advance of the 2020 Summer Olympics. He was subsequently named to the roster of the national team for the Americas Qualifying Event. Team USA qualified for the Olympics, but Liberatore was ultimately not named to the roster in part due to the Cardinals' lack of organizational depth. In June, he was selected to represent the Cardinals (alongside Nolan Gorman) in the All-Star Futures Game at Coors Field. Over 22 games (18 starts) with Memphis, Liberatore went 9–9 with a 4.04 ERA and 123 strikeouts over 124+2⁄3 innings. The Cardinals named him their Minor League Pitcher of the Year.
Liberatore returned to Memphis to begin the 2022 season. After going 3–3 with a 3.83 ERA and 46 strikeouts over forty innings, the Cardinals announced on May 19 that they would be selecting his contract and promoting him to the major leagues. He made his MLB debut on May 21 as the starting pitcher versus the Pittsburgh Pirates, throwing 4+2⁄3 innings and giving up seven hits, four earned runs, and two walks while striking out three. They optioned him back to Memphis the next day, but he was recalled one day later after Steven Matz was placed on the injured list. On May 29, he earned his first career win, tossing 5.0 scoreless innings against the Milwaukee Brewers while striking out 6.
Liberatore was optioned to Triple-A Memphis to begin the 2023 season. Over 13 games (13 starts), Liberatore went 4–3 with a 4.18 ERA, striking out 84 batters over 64+2⁄3 innings. In the majors through the 2023 season, Liberatore posted a 3–6 record and a 4.40 ERA with 46 strikeouts in 61+2⁄3 innings.
In 2024, Liberatore posted a 3–4 record and a 3.70 ERA with 76 strikeouts in 86 innings, alternating between the starting rotation and the bullpen.
