Matthew Liberatore Bio
Matthew Joseph Liberatore is an American professional baseball pitcher for the St. Louis Cardinals of Major League Baseball (MLB). Born and raised in the suburbs of Phoenix, Arizona, Liberatore was selected by the Tampa Bay Rays in the first round of the 2018 Major League Baseball draft out of high school. He signed with the Rays and played in their minor league system for two seasons before he was traded to the Cardinals prior to the 2020 season. He made his MLB debut in 2022 and has since continued to establish himself within the league.
Early Life and Background
Matthew Joseph Liberatore was born on November 6, 1999, in Phoenix, Arizona. He grew up in the suburbs of the Phoenix metropolitan area, a region long known for producing baseball talent because of its year-round playing climate. From a young age, he gravitated toward pitching, refining his mechanics and building the kind of work ethic that would later catch the attention of professional scouts across the country.
Liberatore attended Mountain Ridge High School in Glendale, Arizona, where he became one of the most decorated high school pitchers in the state. As a senior in 2018, he posted an 8-1 win-loss record with a 0.93 earned run average (ERA) and 104 strikeouts across more than 60 innings. His performance that spring earned him the Gatorade Baseball Player of the Year award for Arizona, and in January 2024, he was inducted into the Mountain Ridge Athletics Hall of Fame in recognition of his high school legacy.
Path to Professional Baseball
Before his senior season, Liberatore showcased his talent on a national stage when he played in the Under Armour All-America Baseball Game in July 2017. He was named the game’s most valuable player after throwing three scoreless innings, then later represented the United States with the USA Baseball 18U National Team. Although he had committed to play college baseball at the University of Arizona, his performance in 2018 made him a lock as a first-round draft pick.
The Tampa Bay Rays selected Liberatore with the 16th overall pick in the first round of the 2018 Major League Baseball draft. He signed with the team for a $3.5 million signing bonus and skipped college to begin his professional career in the Rays’ minor league system. He was assigned to the Gulf Coast Rays of the Rookie-level Gulf Coast League, posted a 0.98 ERA in eight starts, and was promoted to finish the year with the Princeton Rays of the Advanced Rookie Appalachian League.
Matthew Liberatore Career
Early Career (2018-2019)
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. He spent the remainder of the year with Bowling Green, where he made 16 appearances, including 15 starts. Over 78 and one-third innings, he went 6-2 with a 3.10 ERA and 76 strikeouts, solidifying his reputation as one of the top young left-handers in the Rays organization.
His development in the lower minors convinced the Rays that he was a cornerstone prospect, and the St. Louis Cardinals came calling during the offseason. On January 9, 2020, the Rays traded Liberatore, along with Edgardo Rodriguez and a Competitive Balance Round B draft pick, to the Cardinals in exchange for José Martínez, Randy Arozarena, and the Cardinals’ Competitive Balance Round A draft pick.
St. Louis Cardinals Breakthrough (2020-2022)
Liberatore did not play in a minor league game in 2020 due to the cancellation of the season caused by the COVID-19 pandemic. He did, however, compete for a spot on the United States national baseball team in advance of the 2020 Summer Olympics. Although Team USA qualified for the Olympics, Liberatore was ultimately not named to the final roster in part because of the Cardinals’ lack of organizational depth. In June 2021, he represented the Cardinals alongside Nolan Gorman in the All-Star Futures Game at Coors Field.
Assigned to the Memphis Redbirds of Triple-A East for the 2021 season, Liberatore went 9-9 with a 4.04 ERA and 123 strikeouts over 124 and two-thirds innings across 22 appearances, including 18 starts. The Cardinals recognized his season by naming him their Minor League Pitcher of the Year. He returned to Memphis to begin 2022, going 3-3 with a 3.83 ERA before the Cardinals announced on May 19 that they would be selecting his contract and promoting him to the majors.
Liberatore made his MLB debut on May 21, 2022, as the starting pitcher against the Pittsburgh Pirates, throwing four and two-thirds innings and giving up seven hits, four earned runs, and two walks while striking out three. He was optioned back to Memphis the next day but was recalled one day later after Steven Matz was placed on the injured list. On May 29, 2022, he earned his first career win, tossing 5.0 scoreless innings against the Milwaukee Brewers while striking out six.
St. Louis Cardinals Era (2023-Present)
Liberatore was optioned to Triple-A Memphis to begin the 2023 season, where he went 4-3 with a 4.18 ERA and 84 strikeouts over 64 and two-thirds innings across 13 starts. In the majors through the 2023 season, he posted a 3-6 record and a 4.40 ERA with 46 strikeouts in 61 and two-thirds innings, continuing to develop as a starter while bouncing between the rotation and the bullpen.
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. He became a more consistent contributor as the Cardinals leaned on his left-handed arm in a variety of roles throughout the year.
Driving Style and Strengths
Liberatore is regarded as a polished left-handed pitcher with a strong feel for his craft and an advanced pitch mix. He has shown the ability to compete on both sides of the plate, generate swings and misses, and limit damage when working through lineups multiple times. His willingness to embrace a hybrid starter-reliever role has also allowed him to remain a reliable piece of the Cardinals’ pitching staff.
Notable Events and Milestones
Among the defining moments of Liberatore’s career are his first-round selection by the Tampa Bay Rays in the 2018 MLB draft, his inclusion in the high-profile trade that sent him to the St. Louis Cardinals, his MLB debut against the Pittsburgh Pirates in May 2022, and his first career win against the Milwaukee Brewers. He was also named the Cardinals’ Minor League Pitcher of the Year in 2021 and was inducted into the Mountain Ridge Athletics Hall of Fame in 2024.
Matthew Liberatore Family
Family Background and Racing Lineage
Matthew Joseph Liberatore was raised in the Phoenix suburbs of Arizona, where he developed his love for baseball at a young age. Public information about his parents and immediate family remains limited, and he is not publicly known to come from a multi-generational baseball family.
Personal Life
Liberatore has been friends with fellow 2018 first round pick and Cardinals teammate Nolan Gorman since they were five years old, a relationship that has followed both players from childhood all the way to the Major Leagues. Their long-running friendship has become one of the more closely followed teammate connections within the Cardinals organization.
2025 Season Performance
In 2025, Liberatore enjoyed sustained success, becoming a fixture in the St. Louis Cardinals rotation. He made 29 starts and posted a 4.21 ERA, cementing his place as a reliable, durable option in the team’s starting pitching staff. The season marked a step forward in both workload and consistency for the young left-hander.
After bouncing between the rotation and the bullpen in previous seasons, Liberatore’s 2025 role as a full-time starter represented a clear vote of confidence from the Cardinals’ coaching staff. His ability to log innings on a regular schedule gave the club much-needed stability in the rotation and allowed the organization to plan around a defined starting five.
Looking ahead, Liberatore’s 2025 results positioned him as a foundation piece for the Cardinals’ pitching future. With his first full major league season as a starter now complete, the focus turns to refining his late-season execution, lowering his ERA, and helping St. Louis compete deeper into the schedule in the seasons that follow.
