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 made his MLB debut in 2024 after rising through the Cardinals’ minor-league system. Through the early months of the 2026 season, he has emerged as a dependable member of the St. Louis rotation.
Early Life and Background
Michael Steven McGreevy was born on July 8, 2000, in San Clemente, California. He grew up in the same Orange County coastal community and attended San Clemente High School, where he developed into one of the area’s top pitching prospects. As a senior in 2018, McGreevy posted a 2.20 earned run average, drawing attention from college recruiters across the country.
Undrafted out of high school, McGreevy chose to continue his development at UC Santa Barbara. The decision allowed him to refine his mechanics, build durability, and test himself against higher-level college competition. His time in Santa Barbara also positioned him for a rapid rise up draft boards.
Path to Professional Baseball
McGreevy wasted little time making an impact at UC Santa Barbara. As a freshman, he appeared in 29 games primarily as a reliever, going 5–1 with six saves and earning first-team All-Big West Conference honors along with freshman All-American recognition from Baseball America. The versatility he showed out of the bullpen hinted at the stamina he would later bring to a starting role.
His sophomore season was shortened by the coronavirus pandemic, but in four starts McGreevy went 2–0 with a 0.99 earned run average, reinforcing his status as an upper-tier prospect. By his junior year, he had climbed into first-round consideration, finishing 9–2 with a 2.92 earned run average and 115 strikeouts against only 11 walks over 101 and two-thirds innings. The St. Louis Cardinals selected him with the 18th overall pick in the 2021 Major League Baseball draft.
Michael McGreevy Career
Early Career (2021–2022)
McGreevy signed with the Cardinals on July 16, 2021, for a $2.75 million bonus and was assigned to the Rookie-level Florida Complex League Cardinals. After two appearances, he was promoted to the Palm Beach Cardinals of the Low-A Southeast, where he started five games and logged six innings of work. The quick move up the ladder reflected the organization’s confidence in his polish and command.
He opened the 2022 season with the Peoria Chiefs of the High-A Midwest League, going 3–1 with a 2.58 earned run average over 45 and one-third innings in eight starts. That performance earned him a promotion to the Springfield Cardinals of the Double-A Texas League, where he made twenty starts and finished 6–4 with a 4.64 earned run average and 76 strikeouts across 99 innings. The full season at Double-A helped McGreevy adjust to advanced lineups.
Minor League Breakthrough (2023)
McGreevy returned to Springfield to begin 2023 and was quickly elevated to the Memphis Redbirds of the Triple-A International League. Over 27 combined starts between the two affiliates, he produced a 13–6 record, a 4.12 earned run average, and 123 strikeouts across 153 innings. The workload established him as one of the top starting-pitching prospects in the St. Louis system.
Major League Debut and Cardinals Era (2024–Present)
McGreevy opened 2024 back at Triple-A Memphis, where he went 5–7 with a 4.45 earned run average and 138 strikeouts over 150 innings in 20 starts.

In four appearances, including three starts, he finished his rookie campaign 3–0 with a 1.96 earned run average and 18 strikeouts over 23 innings.
He was optioned to Memphis to begin 2025, going 3–1 with a 4.08 earned run average in six starts before being recalled on May 4, 2025.

Through June 19, 2026, McGreevy had compiled a 14–10 record with a 3.70 earned run average and 129 strikeouts in his young major-league career.

His undefeated 3–0 record and 1.96 earned run average as a rookie signaled a smooth transition from the minors. Reaching double-digit career wins before his mid-twenties underscored his growing durability as a starter.

Michael McGreevy Family
Family Background and Personal Life
McGreevy grew up in San Clemente, California, and was a high-school teammate of fellow pitcher Andre Pallante, a connection that later carried into the St. Louis Cardinals organization. He has kept most details of his personal and family life out of the public eye, focusing instead on his professional development. His full name, Michael Steven McGreevy, reflects his California roots and tight-knit family background.
2025 Season Performance
McGreevy’s 2025 campaign began in Triple-A Memphis, where he posted a 3–1 record and a 4.08 earned run average with 25 strikeouts over 28 and two-thirds innings in six starts. His strong early-season numbers earned him a May 4 promotion back to the St. Louis rotation. He continued to refine his pitch mix and command against major-league hitters during his first month in the big leagues.
He was optioned back to Memphis in June and shuttled between the minors and majors several times, a common path for young starters still earning the trust of the coaching staff. On July 21, 2025, McGreevy returned to the Cardinals for another extended look in the rotation. The experience gained from those midseason transitions helped him carry momentum into the 2026 season.
Looking ahead from 2025, McGreevy entered the following year with a clearer role in the Cardinals’ long-term plans. His combination of control, durability, and a low walk rate positioned him as a potential mid-rotation anchor. Continued development of his secondary pitches and consistency across multi-inning outings remained the focus for his 2025–2026 outlook.
