Preston Gómez, born in Central Cuba, embarked on a long and varied career in professional baseball, both as a player and a manager. His journey in the sport began in the minor leagues, where he played as an infielder. Gómez's playing career included stints with several teams, but he never quite made it to the major leagues as a player. Despite this, his understanding of the game and leadership qualities did not go unnoticed.

In the 1950s, Gómez transitioned into coaching and managing, roles in which he would spend the majority of his career. He started as a manager in the minor leagues, where he honed his skills and developed a reputation for his strategic mind and ability to work well with players. His managerial acumen eventually led to opportunities in the major leagues.

Gómez's major league managerial career began with the San Diego Padres, where he was appointed as the team's first manager in 1969. The Padres were an expansion team, and Gómez faced the challenge of building a competitive squad from scratch. Although the team struggled in its early years, Gómez's leadership was instrumental in laying the groundwork for the franchise. He managed the Padres until 1972, after which he moved on to other opportunities.

In 1974, Gómez took the helm of the Houston Astros. His tenure with the Astros was marked by a focus on developing young talent and instilling a disciplined approach to the game. While the team did not achieve great success during his time as manager, Gómez's influence was felt in the development of several players who would go on to have impactful careers.

Gómez's final managerial position in the major leagues was with the Chicago Cubs, where he served as manager in 1980. Although his time with the Cubs was brief, it added another chapter to his extensive career in baseball management.

Beyond his managerial roles, Gómez also contributed to the game as a coach and advisor for various teams. His knowledge and experience were valued by many organizations, and he continued to work in baseball in various capacities until his retirement.
