Early Life and Background
Spencer Drew Schwellenbach was born on May 31, 2000, in Saginaw, Michigan. He grew up in Saginaw and attended Heritage High School, where he captained both the baseball and soccer teams and emerged as one of the state’s top prep athletes.
His parents, Jay and Robin Schwellenbach, raised him alongside three older siblings: two older brothers and one older sister. Schwellenbach developed as a two-sport athlete in Saginaw, earning statewide recognition as a senior after posting standout pitching and hitting numbers for Heritage High School.
Path to Baseball
Schwellenbach committed to play college baseball at the University of Nebraska following a successful high school career that included being named the Michigan Gatorade Player of the Year and the state’s Mr. Baseball as a senior. He had been selected in the 34th round of the 2018 MLB Draft by the Cleveland Indians but declined to sign and instead enrolled at Nebraska to continue his development.
At Nebraska, Schwellenbach arrived as a position player and became a regular in the Cornhuskers’ lineup as a freshman. He continued to develop offensively and, beginning in his junior season, took on a two-way role that added relief pitching to his responsibilities. His two-way production and postseason contributions raised his draft profile and drew national attention.

His sophomore season was limited by the coronavirus pandemic, but he played summer collegiate baseball for the Traverse City Pit Spitters of the Northwoods League, where he hit .356 in 22 games.

The Atlanta Braves selected Spencer Schwellenbach in the second round with the 59th overall pick of the 2021 Major League Baseball draft. He signed with Atlanta on July 19, 2021, for a reported $1 million signing bonus and entered the Braves organization as a pitching prospect with a proven two-way background.
Shortly after signing, Schwellenbach underwent Tommy John surgery to repair the ulnar collateral ligament in his pitching elbow. The surgery required a lengthy rehabilitation that caused him to miss the entire 2022 season while he recovered and rebuilt arm strength under the Braves’ medical and player development staff.
Atlanta Braves Organization and Minor Leagues (2023–2024)
After rehabbing from surgery, Schwellenbach returned to game action in the Braves system in 2023, beginning the year with the High-A Augusta GreenJackets. He performed well enough to be named to the 2023 All-Star Futures Game, signaling his re-emergence as a rising prospect in the Braves’ pipeline.
Entering 2024, the Braves advanced Schwellenbach through their minor-league levels. He spent time with the High-A Rome Emperors and the Double-A Mississippi Braves, assembling a strong run that included a low earned run average and an elevated strikeout total across his starts prior to his promotion to the major leagues.

Later that month, on June 28, he produced a career-high 12 strikeouts over seven innings in a 6–1 win over the Philadelphia Phillies.
During the 2025 season he also encountered an elbow injury that led to a placement on the 15-day injured list on July 2 with a fractured elbow and a subsequent transfer to the 60-day injured list on July 6 while the Braves managed his recovery timeline.
