Dave McCarty's journey in Major League Baseball began when he was selected by the Minnesota Twins in the first round of the 1991 MLB Draft. A promising prospect out of Stanford University, McCarty was known for his power-hitting capabilities and defensive skills at first base. He made his MLB debut with the Twins on June 17, 1993, stepping onto the field with high expectations.

During his time with the Twins, McCarty showed flashes of his potential but struggled to find consistency at the plate. Over the course of three seasons, he played in 187 games for Minnesota, hitting a modest .241 with 12 home runs. Despite his challenges, McCarty's defensive prowess was evident, and he was often praised for his glove work at first base.

In 1995, McCarty was traded to the San Francisco Giants, where he continued to seek stability in his career. His tenure with the Giants was brief, as he played only 22 games before being traded to the Seattle Mariners in 1996. With the Mariners, McCarty found limited opportunities, appearing in just 13 games. His journey through the majors was marked by frequent transitions, as he sought to establish himself as a reliable player.

McCarty's career took another turn when he joined the Kansas City Royals in 1998. Over two seasons with the Royals, he played in 147 games, hitting .246 with 15 home runs. While his offensive numbers remained modest, McCarty's defensive skills continued to be an asset to his teams. His ability to play both first base and outfield provided some flexibility, though he primarily remained a first baseman.

In 2000, McCarty signed with the Tampa Bay Devil Rays, where he played 45 games. His stint with the Devil Rays was followed by a brief return to the Giants in 2002. However, it was with the Boston Red Sox that McCarty found a more stable role. Joining the Red Sox in 2003, he became a part of the team during a significant period in their history.

While McCarty was not a regular starter for the Red Sox, he contributed as a bench player and occasional starter. His time with Boston included the memorable 2004 season, when the Red Sox broke the "Curse of the Bambino" and won their first World Series in 86 years. McCarty's role on the team was primarily as a backup, but he provided depth and experience to the roster.

Throughout his career, McCarty was known for his professionalism and work ethic. Despite not achieving stardom, he remained a respected figure in the clubhouse and was valued for his team-first mentality. His career statistics include a .242 batting average, 36 home runs, and 175 RBIs over 630 games.
