Kevin Elster, a shortstop known for his defensive prowess, began his Major League Baseball career with the New York Mets. Drafted by the Mets in the second round of the 1984 MLB Draft, Elster quickly rose through the minor league ranks, making his MLB debut on September 2, 1986. His early years with the Mets were marked by his role as a reliable defensive player, contributing to the team's depth during their 1986 World Series championship run, although he did not play in the postseason.

Elster's defensive skills were his hallmark, and he set a National League record for shortstops by playing 88 consecutive errorless games from September 1988 to July 1989. This streak highlighted his consistency and reliability in the field, earning him respect among his peers and coaches. Despite his defensive capabilities, Elster's offensive production was often a topic of discussion. His batting average fluctuated throughout his career, with his best offensive season coming in 1989 when he hit .231 with 10 home runs and 55 RBIs.

Injuries plagued Elster's career, particularly in the early 1990s. After a shoulder injury in 1992, he missed the entire 1993 season, which led to his release from the Mets. He then signed with the Los Angeles Dodgers in 1994, but injuries continued to hamper his performance, limiting his playing time. Elster's journey through the majors saw him play for several teams, including the Texas Rangers, Pittsburgh Pirates, and the Dodgers again, as he sought to revive his career.

A notable resurgence occurred in 1996 when Elster joined the Texas Rangers. That year, he achieved a career-high 24 home runs and 99 RBIs, showcasing a surprising power surge that defied expectations. His performance helped the Rangers secure a playoff berth, marking a high point in his career. However, this offensive outburst proved to be an anomaly, as his numbers declined in subsequent seasons.

Elster's career took another turn when he signed with the Pittsburgh Pirates in 1997, but his time there was short-lived. He returned to the Dodgers in 1998, where he played his final two seasons. In 2000, Elster retired from professional baseball, concluding a career that spanned parts of 13 seasons. His legacy in the game is defined by his defensive skills and the perseverance he showed in overcoming injuries to remain a part of the major league landscape.
