Luis Quiñones, a Puerto Rican infielder, played in Major League Baseball (MLB) primarily during the 1980s and early 1990s. Born on April 28, 1962, in Ponce, Puerto Rico, Quiñones began his professional baseball journey when he was signed by the Oakland Athletics as an amateur free agent in 1980. His journey through the minor leagues was marked by steady progress, and he eventually made his MLB debut with the Athletics on May 27, 1983.

Quiñones' time with the Athletics was brief, as he played only a handful of games before being traded to the Chicago Cubs in 1986. His stint with the Cubs was also short-lived, and he found himself on the move again, this time to the San Francisco Giants later that year. It was with the Giants that Quiñones began to see more playing time, appearing in 92 games during the 1987 season. His ability to play multiple infield positions made him a valuable asset to the team.

In 1988, Quiñones was traded to the Cincinnati Reds, where he would spend the most significant portion of his MLB career. His tenure with the Reds was highlighted by his role in the team's 1990 World Series championship. Although not a regular starter, Quiñones provided depth to the Reds' infield and contributed to the team's success with his defensive skills and timely hitting. During the 1990 season, he played in 83 games and posted a batting average of .244.

Quiñones' performance in the postseason was particularly memorable. In the National League Championship Series (NLCS) against the Pittsburgh Pirates, he delivered a crucial pinch-hit single in Game 6, helping the Reds secure their place in the World Series. The Reds went on to sweep the Oakland Athletics in the World Series, earning Quiñones a championship ring.

After the 1991 season, Quiñones' time with the Reds came to an end, and he was traded to the Minnesota Twins. His stint with the Twins was brief, as he played only 12 games before being released in 1992. Following his release, Quiñones' MLB career came to a close, and he returned to Puerto Rico, where he continued to play in the Puerto Rican Winter League.

Throughout his MLB career, Quiñones was known for his defensive versatility, able to play second base, third base, and shortstop. While his offensive numbers were modest, his ability to contribute in various roles made him a valuable player on the teams he played for. His career batting average stood at .226, with 19 home runs and 106 RBIs over 451 games.

After retiring from professional baseball, Quiñones remained involved in the sport, taking on coaching roles in Puerto Rico. His experience and knowledge of the game allowed him to mentor young players and contribute to the development of baseball talent on the island.
