Michael McGreevy Bio
Michael Steven McGreevy (born July 8, 2000) is an American professional baseball pitcher for the St. Louis Cardinals of Major League Baseball (MLB). A right-handed starter, he came up through the Cardinals organization after being selected in the first round of the 2021 MLB Draft out of UC Santa Barbara. He made his MLB debut in 2024 and has continued to bounce between the Cardinals and their Triple-A affiliate in Memphis.
After his first taste of the majors, McGreevy earned a permanent place in the St. Louis pitching conversation. His combination of size, command, and poise on the mound has made him one of the more promising young arms in the organization.
Early Life and Background
McGreevy grew up in San Clemente, California, a coastal city in Orange County known for producing athletes. He attended San Clemente High School, where he developed into one of the more intriguing pitching prospects in Southern California. As a senior in 2018, McGreevy posted a 2.20 earned run average (ERA), drawing attention from college scouts despite going undrafted that summer.
Among his high school teammates was fellow pitcher Andre Pallante, who later joined him in the Cardinals organization. That early connection gave McGreevy a glimpse of the professional pathway even before he reached college, and it shaped the way he approached his craft during his formative years on the mound.
Path to Baseball
After passing on the draft out of high school, McGreevy enrolled at UC Santa Barbara, where he quickly carved out a role in the Gauchos’ pitching staff. During his freshman year, he appeared in 29 games primarily as a reliever, going 5-1 with six saves. His performance earned him first-team All-Big West Conference honors and a freshman All-American nod from Baseball America.
As a sophomore, McGreevy transitioned into the starting rotation and made an immediate impact, going 2-0 with a 0.99 ERA in four starts before the coronavirus pandemic cut the season short. He returned for his junior year as a projected first-round talent, finishing the campaign with a 9-2 record, a 2.92 ERA, and 115 strikeouts against just 11 walks over 101 and two-thirds innings. That body of work cemented his status as one of the top college arms in the 2021 draft class.
Michael McGreevy Career
Early Career (2021-2022)
The St. Louis Cardinals selected McGreevy in the first round, 18th overall, in the 2021 MLB Draft. He signed with the club on July 16, 2021, for a $2.75 million bonus and was assigned to the Rookie-level Florida Complex League Cardinals to begin his professional career. After two games, he was promoted to the Palm Beach Cardinals of the Low-A Southeast, where he started five games and gave up six runs on ten hits over six innings.
McGreevy opened the 2022 season with the Peoria Chiefs of the High-A Midwest League and responded with eight strong starts, going 3-1 with a 2.58 ERA over 45 and one-third innings. That performance earned him a promotion to the Springfield Cardinals of the Double-A Texas League, where he finished the year with six wins against four losses, a 4.64 ERA, and 76 strikeouts over 99 innings across 20 starts.
Minor League Ascension (2023)
McGreevy returned to Springfield to open 2023 but quickly moved up to the Memphis Redbirds of the Triple-A International League. Over 27 combined starts between Double-A and Triple-A, he posted a 13-6 record with a 4.12 ERA and 123 strikeouts across 153 innings. The workload cemented his reputation as a durable, innings-eating starter ready for an eventual major league opportunity.
St. Louis Cardinals Era (2024-Present)
McGreevy opened the 2024 season back at Triple-A Memphis, where he made 20 starts and went 5-7 with a 4.45 ERA and 138 strikeouts across 150 innings. On July 31, 2024, the Cardinals added him to the 40-man roster and promoted him to the majors for the first time. That same night, he made his MLB debut as the starting pitcher against the Texas Rangers, allowing one earned run and striking out three in a 10-1 Cardinals win. In four appearances (three starts) during his rookie campaign, McGreevy went 3-0 with a 1.96 ERA and 18 strikeouts over 23 innings.
The Cardinals optioned McGreevy to Triple-A Memphis to begin the 2025 season, where he went 3-1 with a 4.08 ERA and 25 strikeouts across 28 and two-thirds innings in six starts. He was recalled to the majors on May 4, 2025, optioned back in June, and shuttled between St. Louis and Memphis several times during the month before another promotion on July 21.
Driving Style and Strengths
McGreevy works as a traditional power starter, relying on a heavy fastball and a sharp breaking ball to attack hitters. He has shown excellent control throughout his career, walking only 11 batters in more than 100 innings during his junior season at UC Santa Barbara and limiting free passes in the minors as well. His durable frame allows him to eat innings, which has made him a natural fit at the back end of a rotation or as a piggyback option for younger pitchers.
Notable Events and Milestones
McGreevy’s MLB debut on July 31, 2024, against the Texas Rangers stands as his signature milestone to date, a dominant first impression that produced a win and just one earned run. His 1.96 ERA across his first four big league appearances highlighted how seamlessly his minor league command translated to the majors. The Cardinals have continued to use him as a spot starter and bulk reliever, a role that has become increasingly important for a club leaning on its young arms.
Michael McGreevy Career Wins
McGreevy has accumulated wins at every level of the St. Louis Cardinals organization, beginning with his first professional victories in the Florida Complex League and Palm Beach in 2021. He posted double-digit win totals in both 2022 and 2023 in the minors before earning his first three major league decisions in 2024 without a loss.
Minor League Highlights
McGreevy’s first professional win came during his brief 2021 stint with the Florida Complex League Cardinals before he moved up to Palm Beach. He added three wins with Peoria in 2022 and six more with Springfield that same year, finishing his first full professional season with a winning record at two levels. In 2023, he tied a career high with 13 wins across Double-A and Triple-A, and he added three more victories at Memphis in 2024 before his promotion.
Major League Highlights
McGreevy earned his first major league win in his debut against the Texas Rangers on July 31, 2024, and added two more victories later that summer to finish 3-0. He continued to add to that total in 2025, splitting time between the Cardinals rotation and Memphis as the organization evaluated his long-term role.
Michael McGreevy Family
Family Background and Racing Lineage
McGreevy was raised in San Clemente, California, and his family has been a steady presence throughout his baseball journey. While his parents have largely stayed out of the spotlight, the support system around him has played a role in his steady rise through professional baseball.
Personal Life
McGreevy continues to be recognized as a young, focused athlete who keeps his personal life private. He has spent his professional career within the Cardinals organization, splitting time between St. Louis, Memphis, and his Southern California roots during the off-season.
2025 Season Performance
McGreevy entered the 2025 campaign as a depth option for the Cardinals after a strong 2024 debut. The club optioned him to Triple-A Memphis to begin the year, where he made six starts and went 3-1 with a 4.08 ERA, striking out 25 over 28 and two-thirds innings. That production kept him firmly in the team’s plans as injuries and rotation turnover created openings at the major league level.
Recalled on May 4, 2025, McGreevy returned to the St. Louis rotation and provided length in both starts and relief appearances. He was optioned back to Memphis in June, recalled again, and shuttled between the two clubs multiple times during the month before another promotion on July 21. The repeated movement underscored how the Cardinals view him as a near-everyday option rather than a long-term minor leaguer.
Heading into the back half of 2025, McGreevy’s outlook centers on sticking in the St. Louis rotation for the remainder of the season. His combination of command, durability, and poise on the mound continues to make him one of the more reliable young arms in the organization, and his major league track record suggests he can hold his own against veteran lineups.
