Seth Brown Bio
Seth William Brown (born July 13, 1992) is an American professional baseball outfielder and first baseman who is a free agent. He has previously played in Major League Baseball (MLB) for the Oakland Athletics / Athletics. Brown made his MLB debut in 2019 and is now a free agent after spending time in the New York Yankees organization. He is recognized for his power hitting and his journey from small-town Oregon to the major leagues.
Early Life and Background
Seth William Brown was born on July 13, 1992, in Klamath Falls, Oregon, and grew up in the same community. He initially attended Klamath Union High School, where he developed his early love for the game of baseball. His family later moved to Medford, Oregon, during his senior year in order to shorten his mother’s commute to work, and Brown finished his high school career at North Medford High School. As a senior at North Medford, Brown was named first team All-Southwest Conference and second team OSAA Class 6A All-State.
He played American Legion ball for the Medford Mustangs alongside Major League pitcher Braden Shipley, building friendships and competition that helped shape his game. Brown then began his college career at Linn–Benton Community College, playing two seasons and earning first team All-Southern Region honors from the Northwest Athletic Association of Community Colleges as a sophomore. He transferred to Lewis–Clark State College on the recommendation of Linn–Benton’s head coach, Greg Hawk.
Path to Baseball
At Lewis–Clark State College, Brown redshirted his junior season due to academic issues before returning to the field for the Warriors. In his only playing season, he earned second team NAIA All-American recognition after posting a .386 batting average, leading the NAIA with 23 home runs, and driving in 82 runs. Brown also scored 78 runs as Lewis–Clark State won the 2015 NAIA World Series, a major achievement for a small college program.
Following that championship run, the Oakland Athletics selected Brown in the 19th round, with the 578th overall pick, of the 2015 Major League Baseball draft. He signed with the Athletics and began climbing the minor league ladder, quickly establishing himself as a power-hitting prospect with a strong approach at the plate.

He appeared in 63 games for the A’s that year, hitting .189/.251/.306 with five home runs, 15 RBI, and four stolen bases before being removed from the 40-man roster and sent outright to Triple-A Las Vegas on June 18.

Notable Events and Milestones
Brown’s most memorable major league moment came on June 11, 2022, when his go-ahead grand slam off Cleveland’s Eli Morgan powered Oakland to a 10-5 win. He also owns the distinction of seeing the lowest fastball percentage of any major leaguer in 2022, a sign of his disciplined plate approach.
