Jack Dreyer Bio
Jacob Andrew Dreyer is an American professional baseball pitcher for the Los Angeles Dodgers of Major League Baseball (MLB). He made his MLB debut in 2025 and is a member of the Dodgers organization after being signed as an undrafted free agent in 2021. A native of Iowa, Dreyer developed through the Dodgers’ minor league system before reaching the majors during the 2025 Tokyo Series.
Early Life and Background
Jacob Andrew Dreyer was born on February 27, 1999, and grew up in Johnston, Iowa. He attended Johnston High School, where he began his path toward organized pitching. The Iowa native later continued his baseball development at the University of Iowa, suiting up for the Iowa Hawkeyes college baseball program.
During the summer of 2018, Dreyer played collegiate summer baseball with the Harwich Mariners of the Cape Cod Baseball League, one of the most prominent amateur summer leagues in the country. The experience sharpened his craft against top-tier amateur competition and helped position him for a professional opportunity. He is the son of former MLB pitcher Steve Dreyer, giving him a direct family connection to the sport.
Path to Baseball
Coming out of the University of Iowa, Dreyer was not selected in the MLB Draft, but his talent attracted the attention of the Los Angeles Dodgers. On August 3, 2021, the organization signed him as an undrafted free agent, beginning his climb through the minor leagues. His college and Cape Cod League experience served as the foundation for his professional transition.
That signing launched a multi-year development arc that would eventually take him from the lowest rungs of minor league baseball to a Major League bullpen. Dreyer’s route reflected the patience of the Dodgers’ pitching development system, with each stop designed to test and refine his skills. By 2024, he had positioned himself for major league consideration.
