Luis Aguayo, a Puerto Rican infielder, played in Major League Baseball primarily during the 1980s. Born on March 13, 1959, in Vega Baja, Puerto Rico, Aguayo's journey to the major leagues began when he was signed by the Philadelphia Phillies as an amateur free agent in 1975. His professional debut came with the Phillies in 1980, marking the start of a career that spanned nearly a decade in the majors.

Aguayo's role with the Phillies was largely that of a utility infielder. He was known for his ability to play multiple positions, including second base, shortstop, and third base. This flexibility made him a valuable asset to the team, allowing him to fill in as needed across the infield. Despite not being a regular starter, Aguayo contributed to the Phillies with his defensive skills and occasional offensive bursts.

Throughout his time with the Phillies, Aguayo was part of a team that experienced both highs and lows. He was a member of the 1983 squad that won the National League pennant, although they ultimately fell to the Baltimore Orioles in the World Series. During this period, Aguayo's playing time varied, but he remained a reliable option off the bench and in spot starts.

In 1988, Aguayo's tenure with the Phillies came to an end when he was traded to the New York Yankees. His time with the Yankees was brief, as he played only part of the season with them before moving on to the Cleveland Indians. With the Indians, Aguayo continued to serve in a utility role, providing depth and experience to the roster.

Aguayo's major league career concluded after the 1989 season. Over the course of his career, he played in 527 games, recording a batting average of .236, with 37 home runs and 135 runs batted in. While his offensive numbers were modest, his defensive versatility and ability to adapt to various roles were valuable to the teams he played for.

After retiring as a player, Aguayo transitioned into coaching and player development roles. He spent time working within the minor league systems of several organizations, sharing his knowledge and experience with younger players. His post-playing career demonstrated his continued involvement in the sport and his commitment to nurturing the next generation of baseball talent.
