Jack Dreyer Bio
Jacob Andrew Dreyer is an American professional baseball pitcher for the Los Angeles Dodgers of Major League Baseball (MLB). Born on February 27, 1999, he made his MLB debut in 2025 and was part of the Dodgers’ World Series championship run that same year. Known by his nickname Jack, Dreyer rose to the majors as an undrafted free agent and quickly developed into a reliable bullpen arm for Los Angeles.
Standing out for his poise on big stages, Dreyer has built his early professional reputation on command, low earned run averages, and the ability to handle high-leverage innings. His journey from small-town Iowa to championship baseball in Los Angeles has made him one of the more compelling recent stories in the Dodgers organization.
Early Life and Background
Jack Dreyer was raised in Iowa and grew up around baseball, which shaped his path toward a professional career on the mound. He is the son of Steve Dreyer, a former MLB pitcher, and that family connection to the sport gave him early insight into what it takes to compete at the highest level.
Dreyer attended Johnston High School in Johnston, Iowa, where he developed as a pitcher and drew attention from college recruiters. After finishing his prep career, he continued his playing days at the University of Iowa, suiting up for the Iowa Hawkeyes college baseball program and refining the skills that would eventually carry him into professional baseball.
During the summer of 2018, Dreyer expanded his experience by playing collegiate summer baseball with the Harwich Mariners of the Cape Cod Baseball League, one of the most respected amateur leagues in the country. The exposure to high-level competition helped him sharpen his craft before turning professional.
Path to Baseball
Coming out of the University of Iowa, Dreyer was not selected in the MLB Draft, leaving him to pursue the professional ranks as an undrafted free agent. Rather than stepping away from the sport, he stayed with it and continued to develop, eventually catching the attention of the Los Angeles Dodgers.
On August 3, 2021, the Dodgers signed Dreyer as an undrafted free agent, officially launching his professional career. The signing gave him an opportunity to move through the Dodgers’ farm system and prove that he could compete against advanced competition despite going unpicked.
His climb through the minors was steady and productive. By showing consistency in the lower levels and posting strong strikeout numbers, Dreyer positioned himself as a pitching prospect worth protecting on a major league roster.
Jack Dreyer Career
Early Career (2022)
Dreyer made his professional debut in 2022 with the rookie-level Arizona Complex League Dodgers. In his first season of pro ball, he was dominant, posting a 1.50 ERA with 13 strikeouts across 12 games. The performance was a strong signal that he was ready to climb the ladder.
The brevity of his 2022 campaign reflected the shortened nature of rookie-level schedules, but the results firmly established him as a name to watch within the Dodgers’ farm system.
Minor League Rise (2023–2024)
Dreyer spent the 2023 season with the High-A Great Lakes Loons, where he posted a 5–0 record and a 2.30 ERA with 79 strikeouts in 54 and two-thirds innings pitched across 42 contests. His work as a reliever helped him build a track record of getting outs at a high rate against younger hitters.
In 2024, he began the year with the Double-A Tulsa Drillers and was promoted midseason to the Triple-A Oklahoma City Dodgers. Across 46 games and 57 and one-third innings pitched that season, he went 5–2 with a 2.20 ERA, 72 strikeouts, and 4 saves, continuing to show swing-and-miss stuff and composure under pressure.
On November 19, 2024, the Dodgers added Dreyer to their 40-man roster to protect him from the Rule 5 draft, a clear sign that the organization viewed him as part of its major league future.
Los Angeles Dodgers Era (2025–Present)
Dreyer made his MLB debut on March 19, 2025, during the Tokyo Series against the Chicago Cubs. In his first outing, he allowed one run on two hits in one inning of work while striking out Michael Busch, getting his first taste of the majors on an international stage.
He earned his first major league win on April 2, 2025, pitching two scoreless innings against the Atlanta Braves. Over the course of the 2025 regular season, Dreyer appeared in 67 games for the Dodgers, including five starts as an opener, going 3–2 with a 2.95 ERA and four saves while striking out 74 batters in 76 and one-third innings.
Dreyer also played a key role in the Dodgers’ postseason run. He made his postseason debut in the opening game of the Wild Card Series against the Cincinnati Reds, entering with the bases loaded and one out in the eighth inning. He walked the first batter to force in a run, then struck out Tyler Stephenson and retired Ke’Bryan Hayes on a pop-up to escape the jam and preserve the Dodgers’ lead. He later added a scoreless inning in the 2025 NLDS and pitched two and one-third innings across two appearances in the 2025 World Series, allowing three hits and a walk but no runs.
Driving Style and Strengths
Dreyer has shown the profile of a multi-inning reliever who can step into high-leverage situations and limit damage. His minor league track record of strong strikeout rates, combined with his 2.95 ERA as a rookie in the majors, reflects a pitcher who trusts his stuff and executes in tight spots, whether used in traditional relief or as an opener.
