Jerry Royster's journey in professional baseball began when he was drafted by the Los Angeles Dodgers in the first round of the 1970 MLB Draft. He made his major league debut with the Dodgers in 1973, marking the start of a career that would span nearly two decades. Royster played primarily as an infielder, showcasing his skills at second base, third base, and shortstop.

In 1976, Royster was traded to the Atlanta Braves, where he spent the majority of his playing career. During his time with the Braves, he became known for his speed and agility on the field. Royster's versatility allowed him to adapt to various infield positions, making him a valuable asset to the team. He was a regular starter for the Braves and contributed significantly to their infield defense.

Royster's best season came in 1982 when he played a key role in helping the Braves win the National League West Division title. That year, he posted a .278 batting average and stole 35 bases, demonstrating his ability to contribute both offensively and defensively. His performance helped the Braves reach the postseason for the first time since 1969.

After his tenure with the Braves, Royster went on to play for several other teams, including the San Diego Padres, Chicago White Sox, New York Yankees, and Atlanta Braves again in a second stint. His career as a player concluded with the Braves in 1988.

Following his playing days, Royster transitioned into coaching and managing. He served as a coach for several MLB teams, including the Colorado Rockies and Milwaukee Brewers. In 2002, he was appointed as the interim manager of the Milwaukee Brewers, becoming the first African American manager in the franchise's history. Although his managerial stint was brief, it marked an important chapter in his post-playing career.

Royster's involvement in baseball extended beyond the major leagues. He also managed in the minor leagues and overseas, including a successful period as the manager of the Lotte Giants in the Korea Baseball Organization (KBO). His leadership and experience were instrumental in guiding the team to improved performances during his tenure.
