Mike Baumann Autographs

Mike Baumann was born on September 10, 1995, in Mahtomedi, Minnesota. He attended Mahtomedi High School where he played baseball, basketball, and football. During his high school career, Baumann was named the team MVP in baseball twice and earned all-state honorable mention honors. Despite not being heavily recruited, he decided to join the baseball team at Jacksonville University.
At Jacksonville University, Baumann was an important pitcher for the team. In his freshman season, he started 15 games and recorded 77 strikeouts. He continued to grow as a player, and in his junior year, he finished with a 3.06 ERA and 123 strikeouts. His excellent performance caught the attention of the Baltimore Orioles, who selected him in the third round of the 2017 MLB Draft.
Baumann began his professional baseball career with the Aberdeen IronBirds, then moved to the Delmarva Shorebirds before settling with the Frederick Keys, where he had a record of 6-3 with a 2.31 ERA in 2019. He continued to excel in the minor leagues, earning a promotion to the Orioles' alternate training site in September 2020. In 2021, he made his Major League debut for the Orioles, pitching six innings against the Yankees and allowing only one run. Baumann is considered one of the top prospects in the Orioles organization, and his promising career has only just begun.
