Mike Vasil Bio
Michael Vasil is an American professional baseball pitcher for the Chicago White Sox of Major League Baseball (MLB). A right-handed starter who has also worked in relief, Vasil made his MLB debut in 2025 after progressing through the minor league systems of the New York Mets and Chicago White Sox organizations.
Born on March 19, 2000, in Boston, Massachusetts, Vasil was a highly regarded amateur prospect who reached the majors through the college ranks. He posted a 5–3 record with a 2.50 earned run average and 82 strikeouts in his rookie season with the White Sox, establishing himself as a young arm to watch in the American League.
Early Life and Background
Michael Vasil grew up in the Boston area and attended Boston College High School, a well-known baseball program in New England. As a high school pitcher, he drew attention from major league scouts and was projected as a potential high draft pick in the 2018 Major League Baseball draft.
Rather than enter professional baseball immediately, Vasil withdrew his name from the 2018 draft and committed to play college baseball at the University of Virginia. The decision allowed him to develop physically and refine his craft against elite collegiate competition in the Atlantic Coast Conference.
Path to Baseball
Vasil spent three seasons pitching for the University of Virginia Cavaliers, where he developed into one of the top college arms in his class. During the summer of 2019, he played collegiate summer baseball with the Orleans Firebirds of the Cape Cod Baseball League, a respected showcase league for amateur prospects.
After three years at Virginia, Vasil was selected by the New York Mets in the eighth round of the 2021 Major League Baseball draft, going 232nd overall. He signed with the organization and began his professional career in the Mets’ minor league system.
