Michael Stefanic Bio
Michael James Stefanic is an American professional baseball infielder currently in the Athletics organization. He has previously played in Major League Baseball (MLB) for the Los Angeles Angels and Toronto Blue Jays. Born on February 24, 1996, in Boise, Idaho, Stefanic began his professional career in 2018 after graduating from Westmont College. He made his MLB debut in 2022 and has built his career on contact hitting, defensive reliability, and steady on-base skills.
Early Life and Background
Michael James Stefanic was born on February 24, 1996, in Boise, Idaho, and grew up in the same city that shaped his early love for baseball. He attended Timberline High School in Boise, where he played locally before moving on to college baseball. His upbringing in Idaho gave him a grounded perspective, and his high school years laid the foundation for the disciplined approach he would later carry into professional baseball.
Stefanic went on to attend Westmont College in Santa Barbara, California, where he continued to develop as an infielder. During all four of his seasons with the Westmont Warriors, he was selected to both the Golden State Athletic Conference’s All-GSAC team and the GSAC Gold Glove team, a sign of his consistency on both sides of the ball. In his sophomore, junior, and senior years, he led the team in batting average at .352, .371, and .392, respectively. In his senior season, he received an honorable mention for the National Association of Intercollegiate Athletics All-American team as a second baseman. He graduated from Westmont in 2018 with a bachelor’s degree in economics and business.
Path to Professional Baseball
Stefanic entered the 2018 Major League Baseball draft but went undrafted, a setback that did not slow his progress. He compiled a résumé and highlight compilation and sent it to 150 to 200 executives from all 30 MLB teams, a self-driven effort that reflected his determination. Los Angeles Angels coach Chris Mosch contacted him while seeking a replacement for an injured player on the Arizona Complex League Angels roster, and Stefanic signed with the Angels as an undrafted free agent on July 19, 2018.
That signing launched his professional path through the Angels’ minor league system. He spent his first professional season in the Arizona League and with the Orem Owlz, batting .351 over 14 games, an early indication that his college hitting translated well to professional baseball. His climb through the minors would eventually lead him to a major league opportunity in 2022.
Michael Stefanic Career
Early Career (2018–2021)
Stefanic’s first full professional season came in 2019, when he played for the Burlington Bees and the Inland Empire 66ers. Over 102 games, he batted .282 with three home runs and 47 runs batted in (RBI), establishing himself as a reliable middle-infield prospect within the Angels’ system. He did not play in a game in 2020 due to the cancellation of the minor league season caused by the COVID-19 pandemic.
In 2021, Stefanic started the year with the Rocket City Trash Pandas before earning a promotion to the Salt Lake Bees. Over 125 games between the two clubs, he batted .336 with 17 home runs, 63 RBI, and 26 doubles, putting together the most productive season of his minor league career. His performance at the Double-A and Triple-A levels set the stage for his first major league call-up the following summer.
Los Angeles Angels Era (2022–2024)
On July 2, 2022, Stefanic was promoted to the majors for the first time, joining the Angels during their road series against the Houston Astros. He made his major league debut the next day, batting sixth and playing second base at Minute Maid Park. He recorded his first major league hit on July 5, a pinch-hit single in the ninth inning off Miami Marlins pitcher Tanner Scott at loanDepot Park, and he scored his first major league run on a sacrifice fly from Taylor Ward. Through his first seven games, Stefanic batted .389 with an on-base percentage of .500, prompting Angels manager Phil Nevin to promote him to the leadoff spot in the lineup on July 12. He was optioned to Salt Lake on July 28 and recalled on September 14.
Stefanic was optioned to the Triple-A Salt Lake Bees to start the 2023 season. In 25 games for the Angels that year, he batted .290 with a .380 on-base percentage and a .355 slugging percentage, adding no home runs and six RBI. The 2024 season began after he suffered a strained left quadricep in spring training, and on April 30 he was transferred to the 60-day injured list. He was activated on May 29 and optioned to Triple-A Salt Lake, and in 40 games for the Angels he slashed .218/.301/.255 with eight RBI. On October 24, Stefanic was removed from the 40-man roster and sent outright to Salt Lake, and he elected free agency on November 4.
Toronto Blue Jays Era (2025)
On November 27, 2024, Stefanic signed a minor league contract with the Toronto Blue Jays. He was assigned to the Triple-A Buffalo Bisons to begin the 2025 season, and on May 9, 2025, the Blue Jays selected his contract, adding him to their active roster. In nine appearances for Toronto, he went 4-for-22 (.182) with three walks. On June 3, Stefanic was designated for assignment by the Blue Jays. He cleared waivers and was sent outright to Buffalo on June 7, and he elected free agency on November 2.
Athletics Era (2025–Present)
On December 8, 2025, Stefanic signed a minor league contract with the Athletics, the Oakland-based franchise where he continues his career. The move gave him a fresh opportunity within a new organization and kept him in the major league pipeline as he entered the next chapter of his professional journey.
Driving Style and Strengths
Stefanic is known as a contact-oriented middle infielder with a patient approach at the plate. His college and minor league track record shows a hitter who controls the strike zone, makes consistent contact, and reaches base at a strong clip. Defensively, four years of GSAC Gold Glove recognition point to a steady glove at second base, and his willingness to send his résumé across the league after going undrafted speaks to a self-driven work ethic.
Notable Events and Milestones
Stefanic’s signature early moment came in July 2022, when his first seven big-league games produced a .389 batting average and a .500 on-base percentage, leading to a promotion to the leadoff spot in the Angels’ lineup. His first major league hit, a pinch-hit single off Tanner Scott, and his first run scored on a Taylor Ward sacrifice fly remain key milestones from his debut season.
